Since I needed a Shoe hanger and wanted to try out topology optimization I simulated the design by @alphacat (from which I also took the cleat which just stays the same). The Strength seems to be really good in the direction of load. Seems a little weak for sideway load, which makes sense, though, since I simulated only for vertical load.

Printed very well, I used tree supports, haven't tried anything else though, might also work with other supports, depending on printer maybe even without any.
