Tamper-Resistant OTP Container
by IWorkInPixels, published
I made these for the tutorial I'm working on regarding generating one time pads with the Adafruit Internet of Things Thermal Printer. You input the serial number of your one time pads into the SCAD, generate an STL, print the plate to nearly the top of the container, pause the print, drop in your printed one time pads, and then complete the print to seal them in. When it's time to use them, break open the container (you'll know which one by the serial number embossed on the outside) and use the pad. Securely destroy (read: burn) any pages which you have used, and then either print a new container for the remainder of the pad, or else just destroy it as well.
(Special thanks to Clothbot for help with the OpenSCAD file.)
And remember, the best thing about one time pads is SKECD NCQPD RAFQP MSIIA.
I design things in my free time, just for fun. If you like my stuff, send me some DOGE. It'll totally make my day! Thank you.
