Fitbit wrist strap loop

thingiverse

This replacement piece is designed to serve as an alternative to the loop that secures the extra wristband on a Fitbit Blaze band. After wearing it for one day, it appears slightly roughened. To improve its feel, I recommend sanding down the edges located next to your wrist. It would be interesting to hear about results from someone who decides to try making this piece out of TPU.
