I bought something like this and it broke on me so I made my own version. Designed to fit on 3/4 inch PVC pipe. Most can be printed without supports just orient it flat on the bed. Pipe attachment might need supports and printed vertical. This is my second version. But I Printed in PLA and the first on didn't warp in the Kentucky Summer heat. I would print with highest infill for max strength. .2 res does just fine. You will need M5 bolts and nuts to fully assemble. Picture is my first one. Added a top plate to cover and hold the cloth to make it look better.
