About this 3D model

This appliance sold for around $100 a decade ago, but I picked one up at Goodwill for $12. I forgot to test it before leaving the store, and when I got home it just clicked like it had a stripped gear. It was quite a pain to take apart, but the last gear before the big one that drives the opener was indeed missing two teeth. Designing this replacement only took 20 minutes, and after 90 or so minutes of printing I had the mechanism working.
