I love @c00lrunnings00's MicroSD card box. It's a fantastic way to keep from losing small things by putting them in larger containers with bright colors.

I've collected a ton of Logitech Unifying receivers over the years, and they've just been sitting loose in drawers. I took a the original design and remixed it to hold unifying receivers, but it could also hold any small USB devices that are at most 7mm tall outside the port itself.

I also made a hollow version for general storage, but I haven't printed it yet.

They're a bit lower-poly than the original model, but it still fits perfectly with the cap.
