Buchi RE 111 spare gear

thingiverse

This spare gear for the worm drive of the Buchi RE 111 rotary evaporator is a critical component. Originally, it was made from delrin or nylon (part number 00565), but since that part has become obsolete, printing a replacement seemed like the most viable solution to keep this equipment operational. The original gear tends to break easily and is the only weak point in this setup. It's pressed onto an aluminum hub, providing a secure fit.
