Mi Band 3 Keeper

thingiverse

I'm using a Xiaomi "Mi Band 3" fitness tracker, and I've found it often slips off my wrist unexpectedly. This usually happens when putting on a coat or accidentally brushing against something. The band is secured by a small peg-in-hole mechanism that's simple to disengage. A clip comes with the Mi Band, designed to prevent the band from slipping out of its loop. By attaching this clip to the band, it becomes much more challenging for the band to fall off unnoticed. The clip can be installed in two ways: first, you can snap it over the Mi Band strap, which helps to curl the strap slightly and make it narrower; second, you can pop the latch button out of the strap, then insert the end of the strap through the loop, slide the keeper onto the strap, and finally replace the latch button. It's essential to note that the open side of the keeper should face away from your arm.
