Camera strap film canister

thingiverse

A handy hack for lugging an extra roll of 35mm film around - just snap it onto your camera strap with ease! To get started, grab a canister case from a used film roll and two sturdy rings that fit snugly together. Begin by slipping one ring all the way down onto the canister, then clip in the bottom ring. Next, slide your camera strap into place between the two rings. Finally, slip on the second ring to secure everything tightly - and you're good to go!
