This is a redesigned Huxley inspired by the Prusa simplified Mendel.
It uses the PLA Bushings like these.
I modified the scad script to use 6mm rods.
(basically just put in 6mm for rod size and 12mm for width)
I have also redesigned the X and Y motor brackets to be able to use nema 14 or 17 motors. The Z now takes 2 nema 14 motors.
I designed it around 1/4" threaded rods and #6-32 bolts. It should work with 6mm rods and M6 bolts, but I'm not sure.
This should work with the same extruders as the regular Huxley. I believe.

Instructions
Frame
Parts you will need:
6 x Frame Vertexes
6 x 10" threaded rods
12 x 1/4"-20 nuts
12 x 1/4"-20 washers
X-Axis
Parts you will need:
Y-Axis
Parts you will need:
Z-Axis
Parts you will need:
Here are instructions on how to put together the Z spring loaded antibacklash nut contraption
Z-spring insertion
You will need a nut that is drilled out just bigger than your rod, like this one.
BOM:
This does not include any of the extruder parts
Printed Parts:
- bar-clamp x8
- belt-clamp x4
- board-clamp x4
- vertex x6
- x-axis-carriage x1
- x-axis-idler x1
- x-axis-motor x1
- y-bushing-holder x4
- y-motor x1
- z-top-motor x2
Motors:
- X motor : Nema 14 or 17 x1
- Y motor : Nema 14 or 17 x1
- Z motors : Nema 14 x2
- Enough bolts to attach the motors(M3 on mine)
Bolts:
- /#6-32 1/2" bolts x22
- /#6-32 nuts x22
- 1/4-20 nuts x A Bunch
- 1/4" washers x A Bunch
- 1/4" Fender Washers x 6 (.75" OD is about right)
Bearings:
- 1/4" bearing x3
(I dont know the part number right now but they are 0.625" OD, which is like 16mm if your building in metric)
Current Bar sizes are as follows
- Triangle frame threaded rod = 10" x6
- Bottom across frame threaded rod = 8" x4
- Top across frame threaded rod = 12" x2
- Z bottom support threaded rod = 12" x1
- Z Threaded movement rod = 8" x2
- Z smooth rod = 9" x2
- X & Y smooth rod = 11" x4
These are just because I got the smooth rod out of some old printers, and scaled the rest around them. All these dimensions should be able to be scaled up pretty easily. I should be able to get about a 6"x6"x4" printable area.
- Kind of important*
I attached the Z drive rods with some pieces of aluminum rod that I drilled through at 5mm and tapped halfway with 1/4-20. And then put a set screw in the side to hold it to the motor shaft. Im trying to make a printable version of this and still have it be as straight.
