Introduction
RepRap Version III "Huxley" is being developed on this and associated pages. It is based on Ed's original Mini-Mendel design, together with a lot of work already put in by ErikDeBruijn and others. Huxley is named, like all RepRaps, after a biologist: Thomas Henry Huxley.
To clarify, Huxley will be Mini-Mendel with some re-designed parts plus more documentation, defined integrated electronics (with alternatives, of course), and a selection of alternative firmware and host software configured to drive it. We will be integrating as much as possible of the work such as Brutis already done on Mini-Mendel.
The machine uses M6 threaded rods and M3 nuts and bolts (as opposed to the M8/M4 used on Mendel) and NEMA 14 Stepper Motors. The reprapped parts are about 30% of the volume of those for Mendel, which is to say it could reproduce three times faster.
Mendel can print itself, and so will Huxley. In addition, Mendel will be able to print Huxley, and Huxley will be able to print Mendel. We will continue Mendel development to turn it into a multi-material machine. Huxley will be a one-material machine, though we will probably also add a Pen Plotter so we can write etch-resist on PCBs and use an Oil Pen to facilitate separation of Support Material for overhangs.
The idea is to develop both Mendel and Huxley in parallel, with Huxley being as cut-down and minimal as possible, and Mendel being the machine with all the fancy capabilities. Huxley will be the fastest replicator. Mendel will be the most versatile.

*Note: Unofficial
I've (Erik) found suppliers for all of the parts, and the estimated cost of the Mini-mendel would be under 350 euros (in Europe).
Note that because the design is not yet stable, you may need to order more to get everything working satisfactory.

Frame and Rails Dimensional Variants
Silver Steel Rod (Drill Rod in the US) is a precision ground rod made from steel that has a slightly higher level of chromium in it to resist a small degree of corrosion. Intended as a tool steel for drill blanks, screwdriver shafts and axles, this is widely and inexpensively available in standard lengths of 330mm (13" UK Inches).
Given its precise specifications and straightness this makes ideal rails for smaller RepRap builds like Huxley.
The rod can be cut down to work with the current Huxley dimensions or alternatively critical Huxley Frame and Carriage components can be scaled up to minimise reworking this tool steel. As this will result in a slightly larger frame, the bed and by implication build space, can be scaled up if you want. Having measured after framing up using the dimensions below it appears that a build bed of at least 200mm by 200mm is possible. Build space will be something less than that though.
All printed parts remain the same. Belt lengths will have to be increased to suit.
I (aka47) am currently working with a build using these critical modified dimensions for the M6 Allthread components:-
| Dimension | Mini Dim | Huxley SS Dim | Huxley SS All-Thread | Qty Needed | Comment |
|---|---|---|---|---|---|
| J1 | 200mm | 270mm | 314mm | 6 | Frame sides, the two equilateral triangles. |
| J2a | 140mm | 200mm | 245mm | 4 | Frame bottom cross bars |
| J2b | 140mm | 200mm | 335mm | 2 | Frame top cross bars |
| * | * | * | 292mm | 2 | Z Axis Lead Screws |
| * | * | * | 320mm | 1 | Z Axis Base Plate Rod A |
| * | * | * | 295mm | 1 | Z Axis Base Plate Rod B |
Mini Dim, is the dimensions as described in the Mini-Mendel Mechanical Construction Notes. Basically the dimensions that Huxley is based on.
Huxley SS Dim, is how much bigger the component was scaled to minimise cutting of the Silver Steel M6 Rails.
Huxley SS All-Thread, is a suggested length of the M6 Threaded Rod for that part including some for components and fixings. This may vary a bit depending on the plastics you are using but the dimensions here worked for me.
Using these critical dimensions the X and Y Silver Steel rails do not need cutting and can be used as is. You may choose to shorten the Z axis rails a little.
All in all the final dimensions look to have worked out so as to give a bed size very similar to those first achieved by Whosawhatsis?

Printed parts
- Check Mini-Mendel Variation for updates and improvements.

Steppers
Standard 3x NEMA 14 and 1x NEMA 17 (extruder) steppers. Smaller and less expensive than on the full sized Mendel.
Extruder
The MiniMendel uses a bowden-extruder that has less moving mass and thus higher speed due to the stepper not being on the print-head.

Nuts and bolts
All metric and obtainable from mcmaster in the US, and in every home-improvement-store in the rest of the world.
Having built a frame using all nyloc nuts I (aka47) would advise caution for anyone else considering going down this road. Nyloc's are great but a real pain when you need to place them a long way along a threaded rod. The main issues were binding and stripping of threads. Next time I build I will be using standard nuts and anti-shake (star) washers.
Thick sheets
These 2 sheets can be cut from plexiglass or wood with simple tools.
- Erik
- I've printed all RP parts in ABS, they weigh about 300 g. This means you can print 2 sets with your first kg of ABS if you use rafts.
- Update: Mini-Mendel built and working!
- Main development seems to be going on in the RepRap-forum and on Thingiverse.
- German sub-forum
- Thingiverse items tagged "Huxley"
- RustySpoon has created a set of single .
stl parts files from the original repository design files.
- Marcus Wolschon created a Shelled Mini-Mendel that only required 110g of ABS and less then 10h to print. (It may be filled with epoxy after printing but that is not required in all cases.)
- Marcus Wolschon contributed a number of individual reoriented parts to make printing them easier.
- Mini-Mendel/Spacexula Documented Build
- The Mini-Mendel is the first step in optimizing replication time; further steps in that direction are discussed at RepRap Breeder.
- Whosawhatsis? has Redesigned Y-Bar Clamps for Huxley (and Mendel) to print in one piece and require no screws. Instead, the nuts on the threaded rod are tightened-down on piece to clamp the smooth rod.
- Whosawhatsis? has Pulley Extenders to fix the x-belt alignment so that it no longer rubs against the carriage. There are also replacements for x-blunt-plate_1off.stl and x-motor-end-clamp_1off.
stl that have these extenders integrated. Note that these are not symmetric, and the L-shaped portion is designed to align with the belt clamps on the carriage. The carriage is backwards in Erik's picture above.
- Erik has designed a Belt Extension Clip so that the pulley extenders can be used without a longer belt.
- Whosawhatsis? has designed an Idler Pulley for Huxley (and Mendel), suggested by Erik, to replace the mudguard washers on the belt idler bearings.
- aka47? has contributed revised dimensions for M6 frame rods based on using off the shelf lengths of Silver Steel (US Drill Rod) with minimal cutting for axis rails.
- nophead has contributed improved drive pulleys for the Mendel. As Huxley uses the same belts these are also a good idea for huxley.
- RustySpoon has contributed a pair of Bowden nut couplers so that Wades Extruder can be used together with the Mini-Mendel as the Feed for the Bowden assembly.
Again these parts are use-able for a Huxley build
- nophead has contributed an improved drive gear and beefed up idler plate for the Wade Extruder. If this extruder mechanism is being used to feed the Huxley Bowden assembly then these parts are recommended.
