About this 3D model

This is a mashup of Greg's and the modified Arcol carriage. It keeps the original dimensions of Greg's X carriage with the wide belt mounts (so you can use shorter belts if you accidentally cut them too much like me). Parts added: 4th bearing fitting, more holes for mounting the extruder, round hole for nozzle The belt groves are modified for GT2 but you can change it in the scad.
