Shower curtain hooks

The hooks have an a octagonal profile, meaning they can be printed flat and without supports, since the 45 degree overhang of the octagonal profile can be handled by most 3D printers without the need for supports. I have printed these in both PLA and PETG and both print fine. They have been working fine for my shower curtains for more than a month. The 3mf file contains a first plate that has 12x shower curtain hooks that have a smaller 2.3 mm inside radius at the top, suitable for hanging on a thin wire, and a second plate that has a single hook with a larger 4.8 mm radius, suitable of hanging the end hook on the wire bracket (see photos).

In those STP and STL files there is also an oval shaped hooks that would
