Summary

The keyring key carrier for my Thetis FIDO U2F USB key broke, so I threw one together in Tinkercad. I printed it in PETG at 0.12mm layer height and 100% infill, however the layer height is less important than the infill. Since the pieces are relatively thin (same thickness as the original carrier), it will probably end up printing at 100% infill no matter what you set it to.
