A 3D printable light load strap loop with a push pin connection. Sized for 1/2", 3/4" and 1" strap/velcro. Good for attaching straps through a hole in fabric/leather/thin metal less than 2.5mm thick. The two parts snap together very easy and stay together unless you break the pin. I have printed and used this several times.
Print as show with 100% in-fill and no supports. I print the flat clip at draft height and the pin at normal height. can print both parts in <10 min.
If you want me to tweak this design for your needs leave it in the comments and I will add the STL to this group.
