We found a brand new looking Euro-Pro toaster oven a Goodwill for $5, and we noticed at the store that the bottom button was missing. After doing some research we found that this is a great oven, but the biggest complaint was busted knobs, so we snatched it up.

Thankfully Seankmc had already modeled the bottom timer button. After closer inspection when we got home though, we noticed that the middle dial was also broken and not functioning. The tricky guys at Euro-Pro decided to make 3 different knobs with 3 different shaft cutouts and different rotation angles so customers would have to go back to them for replacement. Thankfully 3D printing solves that.

I took Seankmc's original design, to keep continuity and replicated the middle and top knobs. I printed in PLA and they are holding up fine, but if they break, I'm sure PETG or ABS will work best.
