Small metal knobs for manual stages
I'm having no luck finding small metal knobs for replacing some knobs on several goniometers and XYZ stages which have belt gears. I want to use these stages manually, not with a belt-driven pulley system. I think most of these are 3mm shaft but some may be larger or smaller. Where can I find small metal knobs for round shafts with dual set screw locks? I've tried looking around in various places but so far no luck. Any advice?

A couple of my goniometers came with timing belt pulleys already mounted. They looked a little funky but functioned fine as knobs, so I just left them.
Alternatively, you might consider 0.200" = 5.08 mm, for example DigiKey's https://www.digikey.com/products/en/har ... d=&pv73=52 .

This seems to be more what you're looking for:

The hole is unthreaded and it includes a set screw.

For Dean's knob,
You probably know K&S brass tube:

The quarter inch size is a close slide over 5.57mm
Slit longitudinally it may be ok to use on 5mm shaft?
