Bultaco front speedo drive gear (late model Alpina)

thingiverse

I decided not to purchase a new gear and instead utilized Fusion 360 along with a handy helical gear plugin to rapidly create this speedo drive gear from images I discovered online. Initially, I only had the mating part in hand. To fabricate it, I employed 100% fill with PLA material, and fortunately, it has functioned seamlessly so far. However, I did need to drill two small holes into it to securely attach it to the wheel hub using pins. If this gear does fail, I plan to attempt printing it again with nylon as a replacement material.
