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 #632 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

Parts you will need:
Here are instructions on how to put together the Z spring loaded antibacklash nut contraption
Zspring 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:
 barclamp x8
 beltclamp x4
 boardclamp x4
 vertex x6
 xaxiscarriage x1
 xaxisidler x1
 xaxismotor x1
 ybushingholder x4
 ymotor x1
 ztopmotor 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:
 /#632 1/2" bolts x22
 /#632 nuts x22
 1/420 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 1/420. 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.
