Belt Drive Wade's Extruder

Why? Cuz it's retro! Hipsters like Bre will show up at your door just to tell you how cool your extruder is.

Actually, belt drive has several advantages over printed gearing.
- gears don't wear out
- backlash-free
- smoother operation
- easier to tightly clamp gt2 pulleys onto the motor shaft
- less friction

This mod changes the motor mount to accommodate belt tensioning and includes a motor-side bearing brace. Mounted on UConduit (shown). I'll be making one for my MendelMax and
