Keep proprietary files, embarrassing diary entries, and personal documents safe by putting them on an encrypted micro SD card. The tamper-evident design lets you feel sure nobody has attempted to access your files without your knowledge. Inspired by the lock picking lawyer on youtube.

Tested 15+ times with no data loss or damage to the SD card. For data safety, keep the bed under 85 °C. 

Best hidden when using dark opaque filament.
