This is as faithful a model as I could make of the great Davies 1900H knob, of vintage synth fame.
I printed these in PLA at the finest resolution I could on my printer, and at 100% infill. With those settings they are (perhaps obviously) sturdy, solid little pieces of plastic. These are, like the originals, sized for ¼" (6.35mm) knob shaft diameters. They have a set screw hole that will take an M3 screw, but they are not threaded for it. In PLA the plastic was soft enough to tap threads into with the screw itself.
There are two versions of the knob here: A faithful recreation of the original with a recessed indicator line and a version with a raised indicator that is high enough above the body of the knob to allow printing it in a contrasting color without excessive filament changes. Of course, you can paint either indicator as well.
With 100% infill each knob takes about 1.8g of filament. With 25% infill each is about 1.4g, so not a huge difference, even when printing a few dozen--at 24 knobs the difference is less than 10g, and well worth it for the solid feel 100% infill gives.
Happy knob twiddling!
