Prusa I3 X-carriage (Wades)

X-carriage for wades extruder. Bolts together with M3 bolts for Lm8uu bearings. Strong and lighter than most x-carriages I've found.
UPDATE: X-carriage 2 closes off the channel for shorter bridging without support
UPDATE 2: X-carriage 2.1 closes off the channel for better bridging, also allows for press fit bearings and a better fit for the belt. The platform is slightly higher and overall works better than x-carriage 2
