Knob replacement for range hood

A replacement knob designed to be printed in PLA.
V4 has been tested extensively on an IKEA fume hood and a Whirlpool fume hood.
After 3 years the PLA got worn and suffered a minor break leading to V5 which should be stronger and has an even better fit.
For keeping it clean painting might be required.

I specifically designed this because all the original knobs break in two in the same way and replacements are 30+ euro.
This is annoying and due to multiple people having this hood in my family I got motivation and fitting opportunities.
Money saved until now is 120 euro if one assumes that my time is free. Now I hope to save other people some too!
