The file 'Replacement Knob For Vintage Steinberger Guitar Or Bass 3D Printer Model' is (STL) file type, size is 1.6MB.
I needed them for my project. Maybe you need them for yours?
Print with supports, bottom of the knob towards the build plate.
Print in Black and white if your printer supports it. They look great that way.
Or print all in black and paint the indicator bar white.
Tap the holes with a 6-32 tap and use 6-32 x .250" set screws or tap with an M3.5 tap then use M3.5 x 6mm set screws.
These are as close to the original vintage knobs as I could get considering I only have pictures to look at.
EDIT
I have added the "True Version" model. I found better pictures of the originals and made a few very minor, but more accurate changes to the overall size and grip ridges as well as orientation of the set screw holes and indicator line. Also the set screws sizes can either be tapped 4-40 or M3 and use 5/32" or 4mm long set screws in this version.
If you found this design useful and feel inclined to contribute any amount, it would be greatly appreciated!
