Smith and Wesson SW22 VICTORY charge pull ring

I liked the idea of the Halo that is sold for this SW22 Victory but at over $50 USD which is about $1000 in Canada ;-( I decided to try and design one.

If you try this and like it PLEASE consider buying the Halo from Tandemkross.

I had some 3mm knurled nuts and 3mm cap screws in the 25-30mm range so I used them.
You could likely embed a 3mm nut in there as well.

PLA worked fine. I used 100% infill.
