Magnifying Glass Grip Ring

I had a couple magnifying lenses lying around that I salvaged from some broken equipment, so I decided to design mounts for them to make them easier to hold and to provide protection from scratching and in the event of a drop. They will need to be printed in TPU (I used 95A Overture in orange) and will need full supports enabled for the overhanging retaining groove to print correctly. STLs and FreeCAD v 1.0.0 project files are included for both 5 inch and 2.5 inch lenses.
