I had installed a ring light on my mill but for some tool holders it cast a shadow. I designed this to (loosely) hold a Voltax 900 lumen LED light I had.
The fit is somewhat loose, I needed this for some precision slotting so didn't take the time to iterate on that. But I do include the .f3d file for your modification in case you need to make it fit different magnets or light.
Magnet holes are 13.5mm 5mm deep.
PLA, 5% infill, back of holder flat on plate.
