Modular carriage for 40x20 rails (using 3 solid V wheels)

Modular carriage for 40x20 rails. It was designed for Tevo Tarantula to replace stock X Carriage. But it can be used for others with rails 4020 and solid V wheels (24mm)
Update: For origial V-slot please check this remix http://www.thingiverse.com/thing:2155251 and use mbot-xc-p1.stl instead of xc-p1.stl

Hotend mount is compatible with mount http://www.thingiverse.com/thing:1438795
and the pack includes remixed reinforced version of stock Tevo Tarantula mount

E3D V6 hotend mount can be found http://www.thingiverse.com/thing:2155251
(mount holes are the same. Take mbot_e3d_m2.stl, mbot_e3d_m1v2.stl )

Carriage is supposed to use 3 wheels. The top wheel is to be tightened by top bolt. (so just screw tension instead of eccentric nuts)
Use nuts with nylon inserts locking to fix wheels
Basic materials:
- 3 solid V wheels
- 3 M5x40mm bolts with 6 nuts with nylon inserts locking for wheels
- 3 regular or with nylon M5 nuts (just to fix axis M5 bolts)
- 6 M5 washers
