This is a bracket that can be used to hang an RC Wing or Plane on the wall. It was designed to print efficiently with no support material.
The bracket fixes to the wall with a single no. 8 screw that allows it to rotate so that it meets the wing profile of whatever you hold with it.
The geometry has just been eyeballed, there's nothing special about it but after testing a number of different models it seems to work well both for wings that lay flat and also that have a fuselage that protrudes beneath the wing.
You need to print 2 for each plane.
