72mm lens cap clip for neck strap 3D Print Model

Summary
I designed this for my Sony, but I’d expect it can work with other brands. I didn’t like the others I saw that are round and bulky when no cap is attached so I designed this streamlined version. I holds tenaciously.
To attach to neck strap, pinch a fold and insert it over one of the three tabs. You’ll have to work it a bit and pull from other side as it is designed to be snug. Repeat for other two.
