Magnetic ring light mount for electronics microscopes

I have an Eakins microscope that sits in a 76mm collar, and I love using it, but the ring light gets in the way of the objective area. If I want to put on or take off the lens cap, or change the objective lens, I have to undo three fiddly thumbscrews, ensure it doesn't fall onto the thing I'm inspecting, adjust the objective, and then fiddle with the thumbscrews again. I finally went and made a magnetic mount so I can move it easily without worrying about it coming loose during operation.

I designed this for my specific microscope mount. Will it work on yours? I have no idea. My 76mm collar has two flat faces about 80mm apart;  the bottom of the scope sits about 20mm below the bottom of the collar; there are M4 threaded holes in the ring light and on the flats of the collar. The threaded holes in the ring light are almost equally spaced around the ring, but not quite, which is why the holes in the ring light portion of the print are so wide.

The magnets are 6mm diameter, 3mm high disc magnets that I originally bought for Voron assembly. If you are building a Voron, you probably have some spares, too. I paused the print in between the 3.80 mm layer and the 4.00 mm layer, popped the magnets in, and resumed the print. They're snug in there, so make sure you get the magnet orientations right!
