X-Axis GT2 Belt Tensioner

thingiverse

I needed a compact solution to tighten the belt along the x-axis. Previous published projects that used screws for tightening were always too bulky, so I opted for a turn screw instead. This design allows me to tighten the belt and hold it in place while adding a zip-tie, making it very compact. I created this design in Fusion 360 and included the source files if you want to experiment with them. For those without access to Fusion 360, I've also uploaded an .stp file for reference. To secure the GT2 belt, I'm using custom-made locks instead of standard zip-ties: [link] and [link]. Print Settings: * Printer: Monoprice Maker Select V2.1 * Rafts: No rafts were used. * Supports: None were added. * Resolution: 0.3mm layer thickness was chosen. * Infill: A moderate infill density of 20% was selected, as the primary stress area is on the thumb screw between the head and teeth. Increasing the infill above this level would not add significant material to that location. Note: One M4 x 30mm bolt will be required due to the increased length for the thumb screw.
