Summary

This is a support ring for 70mm ostomy bag. It fits the build volume for makerbot mini. Create a belt to attach to the side loops using any 1/2" strapping and any tightening or connecting system you like. I used elastic strap, sewing, and some velcro to make it connect. I made it to fit my waist, it doesn't have much adjustment in it. You could use luggage strapping and connectors but they might add bulk, or even just loop a bathrobe belt through the handles and tie a knot in it. Thread your bag through the hole, the ring should put pressure on the front of the plastic where the flexible bag joins the snap ring, or wafer. This will allow you to put even pressure all around to help prevent surprises and add compression to the stoma site if needed. Do not use if you are experiencing herniation, as it may exacerbate the problem if you tighten it too much.
I uploaded a second one, ostomy ring fatter, which is just 5mm smaller center and 2 mm thicker so less likely to bend. I found the original one was lslipping off on one side and bending with use.
