Openbuilds OX CNC Router Belt Tensioner (2mm)

thingiverse

7/24/19 -- Added step files at request. Openbuilds OX CNC router Belt Tensioner by Tklus (v2) gets a major overhaul, adapted specifically for 2mm GT2 belt instead of 3mm pitch. All credit goes to Tklus; posting this in case others need it too. Works perfectly with all three belts - X and both Y axes. Each tensioner requires one 10-24 or 32 x 1" screw, one 10-24 or 32 nut, and four 4-40 x 1/2" screws. The X axis uses four 5x8mm screws already holding the V-Slot in place. For the Y axes, you will need to add four additional screws per belt unless you have mounts with screws going up into that area. It's highly recommended to tap the 4-40 holes with a small tap to avoid any issues. In my first attempt without tapping, the pieces broke (and I was using v1 files by mistake). If you don't have a small tap, you can take a risk or simply make one by cutting axial slots into a screw so the shavings have a place to go instead of escaping.
