Summary

I saw a lot of knobs for my Ender 3 but they where to small or printed to long or didnt fit so i made my own. It is simple, print fast und and fun to use (finally it is very fast to set the temperature from 0 to 200). My button has a diameter of 25.55mm (maybe it fits all Creality buttons, at least all with the diameter). It's very tight (intentionally set to 25,50mm) - should it not fit, just scale it by 1-2%.
