AC-Bot Carriage 2.0

Please consider using Phaedrux's remix of this design -- He has fixed some minor issues and added extra part options to accommodate steppers thicker than 23mm.

=================================================

This is a 3-wheel carriage I've been working on for my C/D/J-Bot. Uses a Titan Aero heatsink and extruder combo, BL-Touch probe, KW-10 microswitch, and 50mm radial fan. You MUST use a low-profile "pancake" stepper as anything larger will not fit.
