I have an existing piece of equipment that has a potentiometer on the side that controls the speed of the machine. I would like to be able to set the speed, then put some kind of cover over the pot to stop anyone from idly twiddling it. I imagine this will take the form of some kind of dome nut.
Does anyone know of anything like what I've described, and where I might be able to get it?
I am not able to remove the pot in this equipment, or move it inside the case.
