This is a lens holder for a lens that is 50 mm in diameter. A
semicircular slot 3 mm wide holds the edge of the lens. Adjust the SCAD
file for the lens and mounting hole dimensions you need . Lens holders
are useful for demos and optical experiments. The specific lens shown in
the photos is "50mm Optical Glass Lens Collimator Plano-Convex for Led
Projector" which is Ebay item 161126916191. On my printer, the slot
ended up at 2.7 mm wide, about 0.3 mm too narrow for the 3.0 mm lens
edge, so I had to scrape it out a bit with a knife point. Unless your
printer is more accurate than mine, you might want to enlarge the slot a
bit in the SCAD
