Holder for swapping lenses caps

The project solves the most common conflict between requirements for operation with multiple camera lenses:
- Safe and convenient fixing of removed cap of each lens on the camera strap;
- Safe connection to the camera, preventing the caps’ loss;
- Fast and simple connection and removal when swapping lenses.
- All the actions performed quickly and “blindly”, not interfering with the process of photography.
