I've only tried this in tpu, use other materials at your own risk.

Recommended settings:

3 Walls
15% Gyroid infill
Normal supports

Same settings for the band and chungus version

the band version was made because I like to charge my pixel buds (pbp 1, idk if the pbp2 are sized differently) off my phone but don't like them sliding around a bunch
the band tends to stay bent after using it, but it goes back to normal after laying the phone flat for a bit
