Dev boards are great… until you try to use them every day. Bare PCBs don’t belong on a keychain — they bend, scratch, and feel unfinished.

This project offers two compact 3D-printable cases, one for RP2040 Pico and one for RP2350 Pico, turning them into practical, portable FIDO2 / WebAuthn USB security keys. With the right firmware, your Pico becomes a real-world authentication device — and now it actually fits in your pocket.

Design highlights:
- Supports-free printing
- Protects the board during everyday use
- Fast, easy assembly

Whether you’re experimenting with 2FA, building a DIY security key, or just want a cleaner, portable form factor, these cases bridge the gap between prototype and usable device.

Two boards, one goal: turn your Pico into a key you can carry and use daily.
