A simple coat hanger that can be broken down into its three constituent pieces for storage or travel. The tolerances are a bit tight, so it can take some work to assemble, but if you assemble/disassemble it a couple of times, it should become easier to work with.

Print one Hangermain and two HangerWings, then slot the wings into the main hanger body. I recommend slotting them in and pulling them out a couple of times to make the process easier, or add some glue if you don't foresee a need to break the hanger down for storage.
