3D print din rail mount
Using 3D printing to enable DIN Rail mounting of control system components? - Control System
ijensen
#1
This last semester, I had an electrical controls lab where we had to design and construct small control panels and boards for industrial motor control in machines. One of the first things that impressed me was that most components that we worked with inside the main enclosure mounted natively to 35mm DIN rail. Before this lab, I had no idea that this level of modularity was an industry standard, hind sight 2020 of course.
However, it dawned on me the other day that using 3D printing, a technology that a lot if not a large majority of teams have, clips and adapters could easily be made to attach control system components to DIN rail in a robot. Now, I understand that in most cases DIN rail components aren’t moving; Especially at the rate that FRC robots, or even FTC robots, are moving. So before I dive into my own tests (already kinda started), has anyone else tried to mount some or all control system components to DIN rail, and how did it turn out in practice?
If it does work, then I also think it would be a good next step in another project I had wanted to start, and make FRC control system components available to use in ePlan (Another great piece of software that I also had an entire class on this semester) so that teams can expedite control system design and documentation to an industry level. ePlan has a 3D design environment that allows almost automated design and documentation of a component layout with generated wiring, but it assumes mounting to a fixed rail with wiring going through a raceway in most cases.

With that response, I’m not going to even keep the thread up. Might make an off shoot thread on the ePlan part though.
Thanks everyone!
EDIT: Looks like after a few responses I can’t take the thread down myself, lol.

Unclosed! I just wanted to add my 2c. DIN rail mounts make a lot of sense - good thinking! Celt-X has been using the linked DIN rail mounts for three years now with no troubles.
One tip I’d make would be to print the clamps in PETG. PLA works, but it creeps under load, so eventually the clamps can slide side-to-side on the rail (they never release though, and we add end stop clamps to prevent sliding). PETG stays springy under load.
There are actually a boat load of DIN rail clamp models on Thingiverse if you want to experiment. Most don’t have the low profile we wanted (our goal is to keep the electronics bay no more than 2" thick to stay within the versachassis), but here are some that I like the look of:

This talk of DIN rail stuff brings back memories of the Rockwell power distribution block that teams were required to route their main power through in 2008 I think it was. Anyone remember that?

I had noticed there was a lot of DIN Rail stuffs on Thingiverse, something that both pleased me greatly and I found unsurprising.
When I mentioned in my first post how I was already starting to test, what I really meant was “Lets throw this small DIN rail clip onto my crappily modded and horribly tuned Ender 3 then make a Chief Delphi post 5 minutes later while it’s still printing.” ¯_(ツ)_/¯
This is how it turned out:
From this Thingiverse page: DIN Rail Cable Clamp by mdkendall - Thingiverse
It’s just a simple cable clip that uses zip ties to secure a power cable along it. I chose this because its small and would allow me to even see if printing the geometry was worth it time wise per part. This took about half an hour of actual printing for the one, and I’m gonna batch print a plate of 10 later today after class. When I get into the lab later today, I’ll test to see if it can attach to DIN rail and report.

I’ve moved to PETG 100% for my personal printing projects.
I’ve loved how easy it is to print with, and how most filaments are easy to tune profiles for, even the cheaper low quality brands.

I was able to sneak down to lab and borrow a couple pieces of scrap bin DIN rail to test on. The clip clicks on securely, and is taken off just as easily. There is very little twist, and what little there is would probably be corrected with a bunch of these stacked up next to each other on the rail.
I did notice on this clip that, when installed, there is a very slight angle bend towards one of the ends. I think this may be resolved by scaling the clip up to 101% in slicer. Test to follow. I also imagine that this could just be a small part and that a flex in the part would not be as noticeably in a larger, more sturdy part.
I printed this clip with 50% infill.

DIN rail is good for many things. In 2015 we used it to hook the edges of totes for lifting. You can also use V bearings to make a nice linear slide. You can also get it in aluminum to save some weight.

Alternative uses! That’s really interesting. That aluminum rail is very inexpensive, I’ll have to order a pack or two.

Just wondering if you have made any changes to your DIN rail system since your post in 2019.
No ONT Champs in 2020 meant I didn’t get a chance to look at your robot. Wish I had seen this DIN system when I was at champs in 2019. Also looking at your previous thread I see no T taps on the Spark Max mount so I am wondering what the solution was there.
nuclearnerd
#17
No changes in the 2020 files, although we’ll probably re-evaluate this year.
There wasn’t space to squish the can bus T-Taps into the spark max mounts because of the extra motor phase wire. We decided to let the taps float (and/or zip tie them down to other cables). That’s something we might revisit too.

This DIN rail is making me think of slotted wire duct used in many electrical cabinets.
Have people found this to be useful or how do teams keep their wires clean and easy to trace. I figured this is similar to the DIN rail since they are often used in conjunction.

Funnily enough, I also used that in my electrical cabinets for my controls projects. I love it, makes messy wiring look so much better! I wouldn’t use DIN Rail without it.

3946 used this in 2015, and I’ve used it for several non-FRC applications. It looks neat, that’s for sure! I’ve found that it’s great for wiring desks, offices, and server racks where the raceway typically gets opened a few times a year or less. For FRC robots, not so much, due to a combination of the frequency of the duct being opened (once or twice per build session, several times a day at competition), the wide variation of long-run wire sizing in an FRC robot (CAN/sensor vs motor power) and that too often, students grabbed way-overlong cables and doubled, tripled or even pentupled inside the duct. Oh, and it’s not inspectable without opening the cover, a problem not only with formal robot inspection, but also in-house QA and troubleshooting.
I’d much rather have something that looks like zip ties every three to six inches, but that can be opened and reused. I’d really like something that had a base that stuck down with double-side tape tape or similar, then had a short (1/2"-1") tab with hook-and-loop hooks on the outside and a longer (3"?) tab on the opposite face with loops on the inside.
Having slots to pass the loop tab through the hook tab and/or back under the base would be a bonus. Easy to secure, easy to inspect without opening, easy to open and re-secure.

These are all great points. I’m glad you brought them up, because I surely didn’t realize them! As for the hook n’ loop strap idea, I know hook n’ loop ties do exist, just not the double sided tape base part… hmm…
