I am a big fan of the CB3000 and the Holy Trainer but I find that the base ring is often pulled away from my body. This often creates less secure feeling as it becomes possible to pull out and it can cause pain in my balls. In the past I have made a harness for the CB3000 out of a modified butt plug harness and it was effective but not realistic for extended wear. Just today I started messing around with a few different rope harnesses for the Holy Trainer. Basically the harness attaches to the top of the base ring, wraps around the waist forms a g-string that then attaches to the bottom of the base ring. I find that this keeps the device snug against my pelvis and adds an extra sense of security. I would love to hear any comments or suggestions people may have on improving my diy semi full belt or if they have any experience doing something similar.
From the photos....it looks like you used a very "light" shock cord with zip ties to attach to the ring. Is that right? if not what materials did you use
