An attempt to decrease the plastic volume and part count to the Huxley as well as simplify assembly. I am making everything M3 & 1/4" but it should work with M6 as well.

This project is mostly abandoned -- don't have the time to properly complete it.

Current build status:
Mostly assembled, but trying out x-axis alternatives. Will update parts as I revise my build.

To do:

• assemble extruder
• compare x-axis alternatives

My parts:
2-way bar-clamp x8
belt-clamp x4
butterfly-motor-coupling x4
carriage x1
pulley x2
vertex/leveling-vertex x4
x-motor x1
x-idler x1
y-bushing-holder x4
y-motor x1
z-motor-vertex x2

Rusty parts:
board-clamp x4
bushings x12

Part descriptions:
belt-clamp

• changed dimensions
• changing holes and traps to M3 (currently a little tight)

butterfly-motor-coupling new

• coupling for z axis motors and threaded rods based on Rob's Auto-centering shaft coupler (http://reprap.org/wiki/Auto-centering_shaft_coupler)

carriage

• thickened fan mount area of carriage
• changing holes and traps to M3 (currently a little tight)

pulley

• modified nut-trap, created hole to slide in assembled screw + nut

vertex new

• simplified vertex

x-motor

• nut traps changed to M3 with hole to slide in assembled screw + nut
• threaded rod traps changed to 1/4"-20
• reduced height & size (3 hole motor mounting)

x-idler

• nut traps changed to M3 with hole to slide in assembled screw + nut
• threaded rod traps changed to 1/4"-20
• reduced height

y-bushing-holder

• removed wings, added nut trap to center
  (trap currently a little tight)

y-motor

• reduced height & size (3 hole motor mounting)

z-motor-vertex

• combined z-top-motor with vertex
• thickened bar mounting clip
  (need to beef up underside by smooth rods, make other minor tweaks)

Optional/alternative parts:
leveling-vertex new

• use instead of normal vertexes
• insert M3 nut & M3x8 screw for leveling

M3 rosette thumb screw new

• fits onto head of M3 bolt
