Parametric OpenSCAD step-up rings for enlarger lenses. I designed these to replace missing Optorings for a Durst Optotris system. Uses BOSL2.
The Optotris has 3 mounting holes: M50, M60 and M65 * 0.75mm. I needed rings to mount my Componon 105 with M32.5x0.5 and Nikkor lenses to this turret.
Most enlarger lenses are threaded using Leica LTM, which is M39 at 1/26th inch with a Whitworth 55 degree thread angle. The pathing for this thread is lifted from BOSL's BSPP pipe threading function, which happens to match LTM thread exactly.
The rings are printable with a 0.4mm nozzle. I printed them on my Bambu A1 using Sunlu matte PLA with a 0.2mm layer height and a height modifier for the threads to set the layer height to 0.08.
Spacer rings are included, to be printed in TPU. These grip your lens so you can turn them slightly in order to place the aperture dot facing you.
I'll probably extend this file in the future with different mounts as needed.
This is the table from the manual showing which rings you need for which focal lengths:
