A very simple coat rack/key hanger depending on how you scale it. Scaling it up to 250mm long will just fit diagonally on an Ender 3 pro bed and makes a good coat rack size. Scaling it down to 100mm long is a perfect little key holder size.

I also posted this over on Thingiverse. So if you have seen that model that is also me I am just re-posting it here as well.
