A friend asked me to make some climate control knobs for his truck. These seem similar to many others I have seen so I am uploading them. 

there are 2 knobs, one has an opening for the indicator stripe one does not.

The files were created by 3d scanning using an einscan se and edited with tinkercad

Print with the knob up and using support. I also used modifiers to make the connection area solid infill and a modifier on the top to add fuzzy skin.
