Fido U2F Plug-Up security key case

thingiverse

I was looking for a way to safeguard my Fido U2F Plug-Up Security Key from getting damaged on its keyring, so I designed this protective case around it. The design allows for easy printing with a 0.4mm nozzle and includes some shrinkage compensation to account for the plastic's tendency to contract during cooling. To ensure a smooth fit, I deliberately made the hole slightly larger in my Security Key itself. Now, my paracord keyring holds securely in place. Instructions: I printed this project on my FlashForge Creator using MakerWare and imported the .stl file with precision. Then, I carefully relocated the object to the build platform, swapped the filament to the left side of the nozzle, changed from default ABS to PLA, and disabled the heated build plate to start printing at a low quality mode with a 0.3mm layer thickness. For users who might have unique settings or different nozzle diameters, the scad file remains available for download, giving you the freedom to adapt it to your needs – even if that means a larger diameter hole in your Security Key when you drill it out :).
