I will say, I started this print yesterday and then started reading the comments/horror stories about the knob breaking and it being a waste of time and material to print this. Needless to say I was worried all night! While I'm sorry to hear the problems others have had I am happy to say that mine came out great! I did spend a few minutes wiggling it before turning the knob for the first time.
All printing info in the make here. Thank you for this thing! https://www.thingiverse.com/make:357362
