Small 2GT Belt Lock/Tensioner

thingiverse

This is originally made for my RK 3D printer: https://www.thingiverse.com/thing:2537454. A very small two-groove belt tensioner/mount/holder/lock that can be used for any purpose, with two versions depending on the belt teeth side. Both versions take M3 nuts from both sides (if needed) and of course M3 screws. When inserting the belts into the tensioners, handle the little lever carefully, opening it very slightly to insert the belt or you might break it (depending on the material used). 07/03/2018, thickened the belt wall by 0.2mm to make the grip even stronger.
