AirPods Pro Case

thingiverse

There are a lot of other AirPods Pro cases, but (having printed one of them) I wasn't really satisfied with the tolerances and overall design, so I ended up designing my own. This one took 17 iterations total to get right, combining the lid and body prints. This case is designed for TPU filament, which will flex over the AirPods to hold itself in place. Rigid materials like PLA or PETG won't work, since they can't stretch. I've tested it with 95A TPU (e.g. NinjaTek Cheetah), and the bottom part stays on great, as does the lid - better than you'd expect considering it's only held on by friction. I haven't tested any other types of TPU, but a softer material (like NinjaFlex) would probably also work.
