This is a custom designed coil winder with the ability to wind coils in many different sizes. It uses an old bicycle tachometer to keep track of rotations.
You only need 3 small bearings, some screws, a threaded rod, washers and nuts - and of course a 3d printer.
It comes with a gear for an optional electromotor (later), but mostly I use an electric drill clamped on the right knob.
