micro x-carriage 2.0 for prusa v2

I designed this x-carriage because it was always a major pain to pull apart the hotend/extruder/x-carriage assembly to do any work on it.

The micro x-carriage is split up in two pieces. One part keeps the belts tensioned even when the extruder/hotend has been removed. The other part lets you remove the extruder/hotend base simply by removing 3 screws.

As long as you have connectors on all your wires, you can easily swap out extruder/hotend combos.

The extruder/hotend base uploaded here is really just a template that can be modified later. It can be used as a starting point for adding mounting holes, etc for whatever extruder/hotend/etc you want.

This is the 2.0 micro x-carriage. The belt baseplate has been beefed up in the center to prevent bending like the v1 tended to do. The other major change is that the belt clamps are now a beefed up left/right pair w/ a little groove where you can tuck back any excess belt.
