This is a simple watch band keeper for a children's Pokémon smartwatch model: POK4231 from Accutime Watch Corp.
I printed with 100% infill at 0.15 mm with Flexfill 98A from Fillamentum so it would print well.
It prints very fast, around 4 minutes. I made it a bit tight so it's not so easy to get lost.
I am also adding the link to the Tinkercad file in case you want to tune it or adapt it for your needs. Maybe it works for other watch models too.
If you like it, please don't hesitate to rate this design and leave a comment/make. Thanks!
