Prusa Verticle Reinforced X-Carriage

A simple, reinforced, no zip-tie version of Prusa i3 x-carriage.
Features a TAZ inspired belt holder (simple yet it works perfectly).

Update V3:
1). No longer uses any screws to hold the x-carriage.

Update V2:
1). Reversed recessed hole that holds the nut (allows you to tighten facing down).
2). Added thickened support and L shaped belt holder to further improve the design.
3). Added side supports to ensure the plastic can't snap under tension.
