Small 2GT Belt Lock/Tensioner

This is originally made for my RK 3D printer: https://www.thingiverse.com/thing:2537454

A very small 2GT Belt tensioner/mount/holder/lock for any purpose, two versions depends on the belt teeth side. They take m3 nuts from both sides (If needed) and of course m3 screws.

When inserting the belts into the tensioners, be gentle with the little lever, open it very slightly to insert the belt or you might break it (depends on the material you used).
