Peugeot heating knob

Replacement part for my Peugeot 205's heating control: Air flow, fan speed and temperature.

These knobs snug on a little pivot with a flat side. The block/Pivot Test file is what i used to get the right dimensions for the hole that fits over the pivot (it took me about 6 iterations to get it right, i didn't want to print 6 whole knobs...)

The three knobs look identical, but in my car they are slightly different: The middle one (fan speed) needed a slightly shorter cylinder-part. The right one (temperature) had the angle of the flat side different compared to the other two. I'm not sure if this is (terrible/French) design or the years of physical abuse i've put my car through. ;->
Anyway, the script allows for easy customization of the dimensions, pivot angle etcetera.

Look at the commentary in the code for more information.
