Modular carriages for 4020 v-slot (for d3m-bot, d-bot, c-bot)

Human: Modular carriages X Y Z for 40x20 mod with Solid V Wheels (openbuilds) on V Slot rails. Redesigned from http://www.thingiverse.com/thing:1839201. I'm using it now in my own D3M-Bot, a remix of the original D-bot at http://www.thingiverse.com/thing:1001065. The carriages are designed to use three wheels - 24mm Solid V Wheels (openbuilds), bigger than those on the original D-Bot/C-Bot. The third wheel is secured by tightening the top bolt, eliminating the need for eccentric nuts. Use M5 nuts with nylon inserts to lock the wheels in place. The X carriage has pre-drilled GT2 mount places; use a belt clamp from http://www.thingiverse.com/thing:1001065. The Y carriage comes in two variants: one without and one with an LED strip, remixed from D-bot. The Z carriage also has two variants, this time with shorter or longer bolts. Parts for the X and Y carriages are interchangeable; the Z carriage is unique. A build guide and materials list will be defined soon; for now, use the reference instructions and materials list from http://www.thingiverse.com/thing:1839201 as a temporary solution. I added an extra 60mm and two 50mm M5 bolts to secure the single Z carriage's wheels. To lock them in place, use M5 nuts with nylon locks. After setting it up, I'm thrilled to say it looks and works like a tank! Update: On March 24, 2017, I added a mount block for the e3d hotend in files mbot_e3d_m1v2.stl and mbot_e3d_m2.stl. The block has an optional fan mount. I also uploaded radial fan and flow corrector files - mbot-radialfan-mount.stl and bot-radialfan-flow.stl. They're for a 50x15 radial fan. Update: On March 18, 2017, I added the steps file.
