A quick and easy tweak to @onethou's excellent thing (https://www.thingiverse.com/thing:2907920), this simply adds a loop to the film reminder, so that the film minder can be affixed to the camera strap's ring so that you don't have to use glue/tape. It also makes it more versatile as it can now be transferred between different cameras.
Finally, I made three different variants.
1) Top oriented loop
2) Left-side oriented loop
3) Right-side oriented loop
