BigCooter GT2 Belt Tension Mount

This is a remix (sorry can't relocate original design, will update when I do) ... I added the tension shoe that bears against the belt, previous design ran the screw into the belt backside. The Tension shoe slides in a dove-tail track well suited to 3D printing. I also lengthened the belt tooth engagement length. The intended use of this part is to integrate it into your 3D designs, or simply screw it to your parts (a spacer is included for this purpose if needed). I have utilized this component on both X and Y carriages, it greatly simplifies attaching the belt and eliminates the need for floating adjustable idler pulleys, overall, it has simplified my 3D printer designs while providing secure belt attachment, and easy tension adjustment. Use an M3 screw for tension adjustor, drill hole to size to 2.5mm, either tap hole or run screw into hole ... this will result in friction between the screw and hole, the screw will not back off ... I do not suggest inserting an M3 nut in there (I hate hard to print nut pockets and nuts that spin around without a wrench on them .... just thread your screws into the plastic, its easier and more serviceable).

Original design resides on Tinkercad. It can be edited there online https://tinkercad.com/things/cnZWWJHe16J
