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
