[4xiDraw] Belt tension with clamps/pitch (hassle free)

Update 26. August 2016 - Updates to the clamp edition

When applying tension to the belt it can occure that over thime the EndY slips further onto the smooth rods, relaxing the belts again. Therefore I updated to v2.
Clamp_tensor_v2.stl and Clamp_EndY_v2.stl have been updated.

Clamp_EndY_v2.stl has been extruded by 2mm and that additional space has been made more narrower preventing the smoothrod from slipping

Holes and slots in Clamp_tensor_v2.stl have been fixed to align now more with the holes and slots from Clamp_EndY_v2.stl

Clamp tension

I had trouble with original belt tension construction. This one should be easy to install.

Pitch tension

This is another version to apply tension to the belt. This uses less screws then the clamp tension version. I haven't tested it because the clamp tension seems to work out fine for now.
