More Cool Things About 3D Printing
From pencil holders to robotic arms, 3D printing can do a whole lot. What might have taken hours, days, and even months to build can now be 3D printed using this technology to create your unique designs quickly. Even though there are a lot of 3d printing ideas for you to start getting things printed, 3D printing technology is still incredibly new to many. So we’re going to answer some of the most common questions about 3D printing and turning things to 3D.
Can 3D Printers Print Metal?
Generally speaking, yes they can! However, the process and the materials used to print metal is slightly different.
In fact, not all printers can print metal. In 3D printing, there are different manufacturing processes. For 3D printing metal, there are three top ways to 3D print—metal-binding jetter, powder bed fusion, and directed energy deposition. These methods use metal powder or metal wires to layer the materials and print the design in 3D. However, 3D printing metal can’t be done at home because of how expensive the machine to support this type of 3D printing is.
When it comes to 3D printing metal, there are people who may choose to use a laser cutter instead. The reason is that 3D printed projects using metal can be costly and time-consuming. However, the two are quite different. 3D printing is an additive process, while laser cutting is a subtractive process. Depending on your needs, those that are looking to create multiple pieces at a quicker pace may choose the laser cutter as it can conveniently cut multiple materials and larger size.
With digital trends of raw and rustic design, you might be considering 3D printing cool things at home with metal.
However, printing metal is extremely costly due to its process and the machinery required. If you’re looking for cool things to 3D print at home with a metal-looking finish, we recommend using materials on the market that can create metal-like 3D printed objects instead. These materials give the illusion that your 3D printed pencil holder or camera mount is made out of metal but without the actual cost.
What Are Some Cool Things 3d Printers Can Do?
One of the cool things 3D printing can do is be used in the field of science for research. Scientists have successfully 3D printed bespoke equipment and even body parts in the laboratory. Using 3D printed human organs, surgeons are able to use this life-like organ to perform practice surgeries. With today’s advanced technology, 3D printed organs also allow surgeons to work on difficult procedures and rare scenarios without real-world consequences, such as bleeding.
Thanks to 3D printing, it has also made highly-customizable prosthesis possible.
One of the coolest things about 3D printed prosthesis is that they can create custom fits for the patient and also a much lower cost. Instead of creating static designs that are “one size fits all”, 3D print gives companies the opportunity to create products that are affordable and personalized. What would have cost lots of money to create is now more accessible thanks to 3D printed prostheses.
Beyond science, 3D printed homes and shelters have also become one of the cool things to 3D print across the world. To address the housing issue around the world, companies have been using this technology to print emergency shelters and 3D printed homes. With this technology, companies and cities can build a community in a much shorter amount of time and for a cost cheaper than traditional home building methods. Each home inside the community can then be purchased at a more affordable cost.
What Would Be Something Cool to Make With a 3D Pen?
If you’re looking for a smaller and more affordable option, 3D pens are a great choice to get your creativity flowing too.
3D pens are affordable, easy to manage, smaller in size, and more practical. Using a 3D pen you can easily turn things to 3D. Design and personalize cool things to 3D using your imagination and 3D pen. From making repairs by using 3D pen as an adhesive to creating pieces of artwork, 3D pens give you the flexibility to draw your ideas immediately.
If you love architecture and buildings, companies have created kits that allow people to replicate architectural structures and other cool things with a 3D pen. For boardgame lovers, you 3D print your own figurines by drawing it with your 3D pen. You can also turn your favorite cartoon show characters or movie heroes into 3D. While a 3D pen allows you to draw 2D things to 3D, their limitation tends to be the size of the project you can make. If you’re looking to 3D print a life-size chair, it may be easier to use a printer because 3D pens may not be able to create something as durable.
What Are Some Cool Things That Take Less Than an Hour to 3d Print?
If you’re short on time and looking for some quick projects, there are lots of cool things to 3D print in less than an hour! In our 3D print list above, projects like the keychain, hinge, handles, bookmarks, smartphone stand, and whistles are some of the cool things to 3D print in less than an hour.
Aside from those things to 3D print, you can also try some of these awesome projects:
- Tangram: A super easy and fun game to play with your kids or friends. If you’re going on a road trip or simply trying to pass time, this 3D printed tangram makes for portable entertainment.

50 3D Print Ideas to Get Your Creative Juices Flowing
You won’t believe what cool 3D printing ideas exist.
Some people are doing wonders with a touch of creativity and a 3D printer at hand. Such ideas can even grow into a legit business.
Let’s have a look.
What to 3D Print?Home-use 3D printers take DIY projects to a whole new level. It’s an innovative way to create something according to your own unique pattern. How brilliant is that? We all need a cool device like that, don’t we?
The working principle is simple—you make a computer model, and it’s printed out layer by layer using polymer resin, wood filament, or even metal. You can print useful objects like hangers or something cool like a dinosaur toy.
Printing three-dimensional items for your household or just for fun sounds like a fantastic idea. Let’s look at some of the best projects to start with.
Beginner 3D Printer ProjectsNow, if you are a beginner 3D print enthusiast, you may want to start with something easy.
Begin with a straightforward model you’ll use to test your printer and skills. Think of it as getting familiar with the device.
We all know how smartphone cables tend to break right at the connection. But if you own a 3D printer, that’s an easy fix.
A cable protector may not be one of the most exciting things to 3D print, but it’s a safe choice for beginners. The model is pretty quick to make, and you’ll find it a handy thing to have in the household.
DiceImage credit: CADENAS SERVICES d.o.o. (CC BY 4.0)
Dice is the perfect variation of the commonly printed calibration cube. It’s pretty easy to print because of its simple shape. The only thing that you have to add is the dots.
So instead of printing a standard cube, try printing dice. You can use it when playing board games and tell everyone you made it.
Cool, right?

The Cali Cat is often used for 3D print calibration. It’s a much more enjoyable element to print than the simple cube.
The cat is among the cute 3D print ideas. It’s also a benchmark model for beginners, which some keep as a souvenir.
If you like it that much, you can create an entire army of Cali Cats in different colors. Who’s to stop you?
ButtonImage credit: kriswillcode (CC BY 4.0)
A simple button for your clothes is another easy-to-make 3D print design. You just have to decide how many holes it’ll have—two or four.
The best thing is that you can choose whatever color you want or even print all buttons in different colors. Here’s to creativity!
Door StopDoor stops usually come in a triangular shape and they’re pretty basic 3D print models.
So no more slammed doors in your home because of drafts.
To make it more complicated, you can try to engrave a word on the stopper. Just play with the 3D printing software and see what happens.
Drink CoasterImage credit: tliu22 (CC BY 4.0)
A round shape, a few millimeters in height, and there you go—you have a drink coaster. Easy-peasy!
It would look much better if you carve some design on it. A few drink coasters later, and you’ll be a pro—no doubt about it.
Pen HolderYou can print all kinds of pen holders. A simple cylindrical shape is the easiest choice.
Another suggestion for cool 3D prints is a pen holder in an asymmetric design that will be one of a kind!
USB CasingYour boring-looking flash drive can be transformed into something fun and colorful. First, measure your USB, then make a 3D computer model with the shape and design you want.
Such personalized cases are practical when you have a few of the same flash drives at home. This way, you’ll be able to tell them apart quickly.
RingPlastic jewelry is among the popular 3D prints since it’s trendy. The improved technology for jewelry printing allows you to make more complicated and precise designs.
As a beginner, you can try the low poly ring. The design is plain but attractive, and rings are small—they can be printed fast and with minimum material.
Chopstick TrainerA chopstick trainer for your kids or yourself is next in line for the 3D printer. You know how tricky it can be to hold those sticks at first.
You don’t have to figure out where to put your fingers anymore. The “fresh-from-the-oven” chopstick trainer will get you used to them in no time.
3D Print Ideas for HomeMaking all kinds of cool stuff for the home is now possible thanks to 3D printing.
Your DIY projects will become much more inspired as well as functional.

A vase may sound like something bland, but you can think of any design you want and recreate it three-dimensionally.
You can play with shapes, colors, engraving, size, etc. As long as you let your imagination roam free, you’ll be able to produce something exceptional.
Stackable OrganizerStackable organization mini-drawers are among some of the excellent 3D printer projects. The design process might take longer, or you can just buy a ready-to-print 3D model.
All in all, such an organizer will collect your household’s knick-knacks in one place. Men will find it useful in the garage for bolts, nuts, screws, flat washers, and other small items.
Napkin RingsImage credit: Aaron @ Paper Cuts & Plastics (CC BY 4.

An official family dinner will look much better with 3D-printed napkin rings. Surprise your guests with something creative—dainty butterflies, cats, swans, or maybe rose hearts. Remember, you can also print holiday-themed napkin rings.
Smartphone HolderA smartphone holder is convenient and also one of the cool things to 3D print. You can choose from numerous 3D models or design it yourself.
If you want to play with the software, make a personalized phone holder in the shape of an animal or a plant. It’ll be fun to see the outcome.
Kitchen Sponge DrainerThe process of 3D printing a sponge drainer is relatively easy—a rectangular base with an outlet and a grid-like second part on four legs that fit in the base. You can skip the grid piece if that looks too complicated. Or you can think of your own 3D model. Sponge drainers come in all kinds of designs.
A self-watering planter is one of the best things to 3D print if you love plants. It’s convenient when going on vacation. And you don’t have to worry about your plant—it’ll be well-watered and alive when you return home.
Start with a small planter for succulents or herbs to see how it goes. Then, you can move to bigger pots.
FunnelA funnel is a functional kitchen item. You probably have one at home. However, you don’t have a 3D printed funnel you’ve made yourself.
Test this idea just for fun—it can even be a mini version to see what happens and how your printer behaves. Even a tiny funnel can find its purpose—e.g., pouring liquid cosmetics from a larger container into a smaller one for traveling.
Egg White and Yolk SeparatorSo many plastic kitchen objects can turn into 3D printing ideas.
Baking often requires egg whites and yolk to be separated.
You can go with the standard spoon-shaped design or try making a double egg white and yolk separator that works with two eggs simultaneously.
BookmarkImage credit: Oxa (CC BY 4.0)
If you love books, make yourself a bookmark. There are so many designs to choose from, or you can create one on your own.
Turn on your imagination to the max. Try creating a bookmark featuring a favorite book character, for example. Who knows, this may rank among your best 3D prints.
SD Card CaseCan’t find your SD cards because they’re too small? We hear you! And they always seem to get to the bottom of the drawer.
With your brand new 3D self-printed case, you’ll put them in order. It will be small enough to fit in your drawer but big enough for you to find it quickly.
Perfection!
The world of 3D printing is vast. You can choose from various cool, fun, or useful ideas. Good rendering software will help you print whatever you want to.
So what are some useful things you can print?
Clothes hangerA clothes hanger is a functional home item you can easily 3D print yourself. That’s incredibly convenient when you need a spare hanger but don’t want to drive to the store.
If you go with a foldable design, you can take it along in your travels. Such a collapsable hanger can easily fit inside a carry-on bag or suitcase.

Want a customized phone case? This is definitely one of the useful things to 3D print.
Just measure your phone and think of a design. The great part is that no one else will have the same phone case, and you can print as many designs as you like.
In the modern home or office, cables are everywhere. And sometimes, they make your space look unappealing and messy. A cable organizer can solve this issue.
When you have all your cables put in order, your space looks great. A 3D printer will help you make the type of cable organizer you need.
WrenchImage credit: HD_Creator (CC BY 4.0)
Believe it or not, the wrench is one of the most popular 3D prints for beginners. This tool can be used straight off the printer.
The adjustable 3D printed wrench can also come in handy in later projects around the house. Anyway, it’s better to have one just in case.
Laptop standA laptop stand is a practical thing to have at home. It serves two purposes—it helps against overheating and holds the laptop at a convenient angle to look at.
When choosing a 3D printing project, you may notice that some laptop stands are one piece while others have multiple parts. Choose one that you have enough skill for. Or… start from scratch with your own model.
Water Bottle OpenerImage credit: bobby (CC BY 4.0)
Sometimes those bottle caps are so hard to open. We’ve all been there. But there is a solution for that—3D printing a water bottle opener.
It gets ten points for usefulness, especially when you’re thirsty, and that cap is so tightly screwed.
Faucet Water SaverThis helpful gadget attaches to the faucet and saves you water. Such faucet attachments are cheap and easy 3D printing ideas because they come with a ready-to-print model and require less filament.
However, you’d have to buy a rubber seal separately, but that’s a quick fix.
Spare KeyA spare key can go into your self-printed collection as well.
That’s quite a useful item to have, just in case.
3D scanners can help you create a precise copy of your key. These devices thoroughly scan physical objects and make exact copies. A spare key is a great starting point.
Q-Tip DispenserA sleek rectangular model with a cover is the go-to design. On the bottom there’s a protruding part that looks like an open drawer. That’s where the q-tips slip for easy access.
Q-tip dispensers are effortless and convenient 3D printer products to try making at home. You can even give them to friends as gifts. They are the DIY version of practical presents.
Survival WhistleImage credit: Plexi (CC BY 4.0)
A survival whistle is a simple object at first glance, but it can save your life. Carry it in your purse or on a keychain for easy access.
Aim for a straightforward and functional 3D whistle design.
Make sure it’s loud, easy to grab, and possibly with a hole to attach to your keychain. Such an item can also be used at sports events.
Now, it’s time to have some fun with your 3D printer. Practical items are great, but fun and cool objects will take your 3D printing to a whole different level.
Let the magic begin:
Magic WandKids will love a present like this. It can be a Harry Potter style wand or one with a star on top. But don’t limit yourself to these suggestions. There are plenty of options to go with for this project.
If you involve the children, they can surely help with some fascinating ideas. Let them add small details to the magic wand with a 3D pen to make the process more fun. Just choose one that doesn’t overheat and prepare a proper workspace. It can become messy.
Hanging Bird FeederImage credit: Shadowcraft Designs (CC BY 4.

Bird feeders are among the cool things to make with a 3D printer for your garden. There are multiple creative designs to suit your taste. Let’s not forget about functionality since their primary purpose is to feed birds.
Searching for food can be a challenge for birds in winter. You can make their life easier with a simple 3D printed feeder and some seeds.
Letter BoardDo you know that a 3D printer can produce an entire letter board? Letters, numbers, board, and frame. All of it!
Letter boards are widespread interior design pieces. You can turn them into fun 3D prints by making colorful letters or a board that’s not the usual black or white.
StampsWith 3D printed stamps, you can genuinely go overboard. Imagine how many stamp forms you can think of. Not to mention what can go on the actual stamp—letters, inspiring words, shapes, etc.
You name it!
Looking for cool things to 3D print? We have a brilliant idea for when you’re bored. Why not print a mini catapult?
It’s not the easiest 3D design. Most likely, it’ll have multiple parts for you to assemble. You may also print some mini cannonballs to make the picture complete.
Well, now you have the whole mechanism. Go ahead and try it!
YoyoImage credit: lolo_aguirre (CC BY 4.0)
We’ve already started with toys, so let’s continue with them.
The yoyo is simply two connected disks with an axle between them and a thin rope. It’s pretty easy to 3D print.
You can add cool engravings to the sides to make it more personalized. Find a good string, and voilà!
Puzzle Plane3D printer products in the form of puzzles are pretty entertaining.
With some thinking, you can make one yourself.
Start with something simple like a plane. The shape is not overly complicated. All you have to figure out is how many parts it’ll have and how to attach them.
If that’s too complicated, you can find a ready model.
Spinning TopImage credit: Fx137 (CC BY 4.0)
You probably haven’t seen that one in a while. It’s another epic toy from childhood. It’s also good for stress relief. Watching a spinning top in action has a calming effect.
Making it part of your 3D printed items collection is not too challenging. It’s one piece and small, so it won’t take much time and material to print.
Avocado Seed FloaterLet’s face it:
You have to be a real plant lover to 3D print a floater for your future avocado tree. Avocado seeds are delicate, so it’s better to initially submerge them in water, not soil.
A seed floater can help with that, so why not print one?
Image credit: MediaMan3D (CC BY 4.0)
Thor’s iconic hammer is an absolute favorite in the 3D printing community. It looks fantastic on display, but making it large might be challenging for a home raisin 3D printer. Try making it in a smaller size, and you should be fine.
Things to 3D Print and SellSelling 3D prints can become a legit income source. You can try to sell your creations if you’re confident enough in them. Why not?
However, due to copyright, be aware that you cannot sell someone else’s design.
Let’s see what can sell well:
JewelryPlastic jewelry is at the peak of its popularity now. 3D printed rings and color-blocked beaded bracelets and necklaces have a good chance of selling.
Beads with letters are trendy this season as well. Glasses chains and plastic earrings are also on that list.
Any jewelry design that’s creative, artsy, and modern will do the trick as long as you can 3D print it.
Headphone HangerYour 3D printing projects can make you a profit if you create unique designs.
Headphone hangers can turn out well on a 3D printer. There are some models available on the internet that look super cool. Get your inspiration from them to make something truly extraordinary.
Moon LampMoon lamps are quite an eye-catcher. The round shape is easy to 3D print. You have to add the Moon surface craters and a stand. Make sure it’s an original design, not copied.
It’s safer to buy the actual lamp-holder that goes inside. You also have to find a way to attach it to the rest of the construction. Try making one for yourself first to see how it goes.
Any unique 3D printed lamp is a good item to sell since home decor is currently popular.
FigurinesImage credit: Rextruction (CC BY 4.0)
Statues and figurines belong to the group of 3D printed items that sell well. You must be careful because they can be classified as copyright content—especially miniatures from movies, TV shows, or video games.
3D models of mythological creatures and animals are fine if you design them yourself. A good idea is to make custom figurines of pets or people. Buyers would love that.
Wall Art3D printed wall art is an excellent substitute for paintings. The creative ideas for such art pieces are endless. They can add texture and originality to plain walls.
Here are some ideas:
- A fairy for a girl’s room
- A tree for the living room
- A coffee cup for the kitchen
- A plane for a boy’s room
A six-pack beer carrier is a cool 3D print idea that might sell.
People could buy it as a fun gift for beer fans. You can also offer custom engraving to make it more attractive for buyers. Personalized items make fantastic presents and are more pricey.
Cookie cutters can be 3D printed in various shapes. And since they are hollow, you won’t use much filament. The production cost will be low.
However, plastic cookie cutter sets’ prices are low as well. You may enter the market by designing unique 3D prints that no one else has. That way, you can charge more for a set of custom cookie cutters.
Plant PotsImage credit: thudbuzz (CC BY 4.0)
Try to choose 3D print models that look luxurious, high-end, and one of a kind. That’s what people would buy. The production method isn’t the main selling point here, but luxury and style are. Keep that in mind.
Plant pots, along with vases, are trendy home decor items that can be printed using a 3D printer.
Wall ClockIf you follow interior design trends, you can think of a wall clock that also serves as an art piece. Your 3D printer will handle the base and the hands of the clock. You can print dots instead of numbers for the hours. It’ll look more classy that way. Buy the turning mechanism separately—it’s far too complicated to make yourself.
Toilet Paper and Phone HolderImage credit: Celta (CC BY 4.0)
Our list of 3D printed items that sell ends with something both fun and useful. Some people habitually take their phones to the toilet, but there is no place to put them. A toilet paper holder with a phone shelf perfectly caters to that need.
Wrap UpThe world of 3D printing stimulates both our creative and practical thinking.
3D printers let you materialize objects in the comfort of your home. And you can even sell some of them.
So are you considering buying a 3D printer? Definitely give it a try!
