My Smeg Oven knobs broke. This is a simple replica made in Fusion360. I suggest you print it in a strong and temperature resistant material such as ABS or PETG. I went with ABS as it is what I had. 

Do not use PLA or it will melt and may break.

V2 - the knob now fits tightly, you will not need glue. Also added a small jut so the knob sits similarly to the others. This will now work for both Oven and Stovetop!
