GT2 Belt Drill-Splice Jig

thingiverse

This is a modified version of the splicer by MaleBuffy, allowing for the use of a drill and pinning the teeth. It's still a work in progress, as I'm waiting on new belts and plan to print and test it soon. Designed to accommodate tiny drills like those used for nozzle cleaning or PCB holes, these are very affordable on eBay (as nozzle cleaners) in sets of 10. This re-mix introduces two key changes. A small 3mm guide hole is centered between each tooth, enabling two belts to be placed and drilled without the risk of drill breaks, while keeping alignment accurate. This modification is likely repeated for 2-3 teeth. Additionally, an opposite 0.5mm hole has been added, allowing a "pin" to be inserted from the other end and tapped into place. While this may not print well initially, it can be drilled out to accept pins smoothly. I'm still figuring out how to remove the pin after insertion, but likely the belt can be lifted enough and the pin clipped. The other change involves adding a couple of slots to the end, enabling accurate "three way" cuts on the belts. Place one belt in and cut twice; repeat for the other belt, then remove opposite portions so they can fit each other. Finally, move to the drill position for the final steps. There are some videos on YouTube demonstrating drilled/pinned splices, which aren't great but convey the idea. This jig is likely to make the process much easier. Once I receive the belts and print this design, I'll report back on its effectiveness and how well the final joint holds. I plan to glue the back as well, so this should enhance durability.
