Fido U2F Plug-Up security key case

thingiverse

This is a case for the Fido U2F Plug-Up Security Key. I was concerned about my Security Key getting damaged on my keyring, so I created this case to go around it. This is designed to print in one pass of a 0.4mm nozzle and allow a small amount of shrinkage of the plastic. I also drilled the hole a bit larger on the Security Key itself so that it would fit on my keyring. I use a bit of paracord for my keyring. Instructions I printed this on my FlashForge Creator. I used MakerWare and imported the .stl file. I told it to move the object to the build platform. Then I switched the filament to the left side and changed the default ABS to PLA. I also turned off the heated build plate. This printed just fine in low quality mode - 0.3mm layer thickness. The scad file is available if you have different settings such as nozzle thickness or your plastic shrinks differently. Maybe you used a different diameter hole when you drilled out your Security Key :).
