I made my own hanger and ads, you already know how to make the homemade bib from the diagram. But I made an ads somewhat like a mini bib(the tubing portion) the entire portion that surrrounds your penis is only about 1 1/2 in. in lngth as opposed to the homemade bib being about 4 in. long.
Anyway I made the hole where the s hook would normally go larger. Ran some theraband through that and tied it in a knot, ran the other end down and around an old belt approx. 8 in. above my knee. For the belt portion, I just took an old belt cut about half off, and drilled some new holes.
The entire process only took about 30 min. and it works perfectly. Also you need a hose clamp to surround tubing just like on the bib, and I take it off for about 30 min every 1 1/2 hours for circulation
