Yamaha PSR-12 music keyboard sliding control knob

thingiverse

This is a control knob for the Yamaha PSR-12 keyboard if you lost one. These knobs come off fairly easily by pulling on them and perhaps is why they get lost. Should work for any of the controls I think (volume, power, select, etc.). I only needed one. It's unfortunately single color unlike the original which is dual color and inset, but this is easier to acquire. I think the STL may contain more detail than can be printed at 0.2mm but YMMV. Though this is small and doesn't use much filament, there's no need for much fill. Use very low fill, 5% is enough, will help draw the top surface "bridge." Please read postprocessing.
