For Westflalia Electrolux refrigerator thermostat knob (Part No. 255070527B)
Used in Westflalia T3 (T25 / Vanagon) and some others.
(I use OpenSCAD V. 2017.11.12)
I added the SCAD files (it's my first object), do not hesitate if you have recommendations ;-)
I tried to print the head (face with marking) down, but the face was not beautiful. I tried the head up with a support, it's much better.
-> For cura: Supports In contact with the tray for 60 ° in ZigZag filling 12%.
Maybe there is something like regulation.
