OP1 Volume Knob

thingiverse

Replacement volume knob designed specifically for Teenage Engineering OP-1 synthesizers. I obtained mine through a second-hand purchase with the original knob missing, so I had to rely on encoder knobs and online photos as reference points. This replacement volume knob is likely compatible with any device featuring a 6mm D-shaft. The knob's outer diameter measures 10.25mm, while its height stands at approximately 14mm. A small margin of clearance has been built into the shaft to account for potential variations in thermal expansion during printing. Depending on your printer and settings, you may need to add a thin layer of adhesive tape to ensure a snug fit between the knob and shaft.
