This is a remix of the excellent PicoKey Case (RP2350/RP2040) DIY YubiKey/Passkey. All credit for the original concept and base design goes to the author — I only adapted the top shell and trimmed everything I personally didn't need.

Tip — getting a solid USB-A fit

Because the PCB is thinner without the USB shroud, some host USB-A ports won't grip the TENSTAR RP2350 firmly enough to make reliable contact. My fix: three layers of standard electrical insulation tape on the back of the PCB. It bulks the board back up to the right thickness for a snug fit, and — bonus — by using different tape colors, you can visually distinguish multiple keys at a glance (handy if, like me, you own several).

Printing notes

  • Layer height: 0.10 mm works great.

  • No supports needed.

  • Any rigid filament is fine; PETG or ABS recommended if you carry it on you (PLA gets soft in a hot pocket or car).
