Cyclo_Tron I am impressed. I would never dare 3D print a hanger unless I was printing in metal.
Nylon is my guess at the better material here, but it is a bear to print on an Ender 3. I printed some nylon in the past on a few FDM printers and it was a mixed bag of results. A lot of warping unless it was a really hot day and I used a very wide raft. Even with an enclosure it needed to be hot in the room. Now a days all my home printing is in resin and that needs consistent climate control.
