This is a lens cap for the (underrated) HTC Re camera. I remixed the original design by robduarte and added a loop for a piece of string. I then made a small attachment piece that slides onto the bottom of the camera, also with a loop for a piece of string. I used a piece of sewing thread to tie the two pieces together. The bottom attachment piece should stay in place when the original (or replacement) lanyard screw is attached on the bottom of the camera.
Highly recommend printing these in TPU, but PLA will probably work, too.
