I modeled and printed some custom zero stop rings for my Vortex Strike Eagle 5-25x56. I figured I would post as I had seen some people asking about custom ones online when I was looking.
I printed in PLA for now, but I am sure that it would be better to print in something with more temperature resistance.
I printed without supports and the deeper groove down for the best results.
