The holder that kept the wristband in place snapped and I made this little thing in Fusion 360. I didn't check Thingiverse first so I see now that there are couple of other versions of this thing already. I tried to make it as small as possible and uploaded two different versions – a 10mm wide as the original, and a slim 8mm version. I like the slim version best :)
