M25 Jam Nut

I have a bunch of enlarger lenses that I kept after upgrading enlargers and I could not find anything to mount my m25 lenses to anything, so they just sat.

Then one day I got a 3D printer and when going through my darkroom stuff asked myself if it could be done, not if it should. So here it is, the elusive jam nut that I haven't been able to find locally or online for a reasonable price.

I'll likely make a lens board to mount my m25s onto a beseler style lens board and also for my Omega C760.
