Summary

These bracelets are compatible with LEGO bricks and should work with other brands as well, although it hasn't been tested.

I've modeled three sizes- the small size is the same length as a LEGO Dot bracelet. The medium is two stud lengths longer, while the large is four stud lengths longer than the small.

I would advise printing in TPU or another flexible filament, unless you want a stiff plate instead of a bracelet :)
