TPU Watch Band Keeper

TPU watch band keeper replacement for watches and fitness bands, sized to fit broken or missing strap loops.

This TPU watch band keeper replacement is sized to fit your strap dimensions, making it a simple way to replace a broken or missing loop without buying a full replacement band.

It works well for watches and fitness trackers, and can also be adapted for other small strap-retention uses like cable wraps, soft gear straps, or similar flexible bands.

Print one part that fits your setup instead of ordering a multipack you do not need.
