Update:
I quit using the metal rings due to pain and issues urinating and thought it was causing those issues(in fact they were related to a tight pelvic floor due to my heavy lifting in the gym).
Came back to the drawing board over the past 2 weeks after seeing the diy silicone sleeve thread. Using my laser engraver, I cut whiteboard rings to fill a pvc tube and create this contraption. I tried just silicone but it only weighed about 4oz and thru hanging with the rings I found 8-12oz seemed to be the sweet spot for fatigue when worn all day.
Testing it today. Getting in was not bad using a noose hanger and a little water. I was able to pull thru and then lock it in with another diy silicone band with a smaller ID(1") OD on the smaller band is 1.5" matching the inside of the sleeve with the rings.
