Just looking to gauge interest and get some input from those more experienced, on something I started playing with the other day. Adding any kind of support straps to my base ring resulted in pinching and irritation. After a few measurements I printed this up and have been testing it. I would be happy to supply step files or try to make alterations for those interested, or just get some pointers on a better design. This idea should work with any of the typical Chinese devices. The current one should fit well with a 40mm ring.
