I needed another watch band than the original, and decided to print one. I used the Apple Watch band from Adafruit and remixed it with some changes:
I used NinjaFlex TPU 85A black which is working very well.
The pins that hold the watchband to the watch is a little hard to get in the watchband
I've been using this for several months without any issues. The TPU is really strong!
8 july 2023 :
Added another version of the strap which is 3 cm (1.2 inches) longer
The author remixed this model.
