BigCooter GT2 Belt Tension Mount

thingiverse

This is a revised model (I apologize for not being able to replicate the original design yet, will update once I do)... I have included the tension shoe that pushes against the belt, my previous design involved running the screw into the belt's backside. The Tension shoe glides in a dove-tail track perfectly suited to 3D printing. I also extended the length of engagement for the belt tooth. This part is meant to be integrated directly into your own 3D designs, or screwed right onto your parts (a spacer has been included in case it's needed). I've utilized this component on both X and Y carriages, and it simplifies attaching the belt greatly, eliminating the need for floating adjustable idler pulleys altogether. Overall, it's made my 3D printer designs simpler while providing a secure belt attachment, 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 cause friction between the screw and hole, ensuring that the screw won't back out... I advise against inserting an M3 nut (I dislike hard-to-print nut pockets and nuts that spin around without a wrench). Simply thread your screws into the plastic, it's easier and more serviceable.
