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 is as of yet untested but should be stronger and have 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!
