Ice PadlockBy Cults on March 15, 2019 00:31report
Simple ice-padlock with M3x10 screw and nut side inserts.
Use Icecubes or fill and put it in the freezer. Make sure to plug the holes with tape.
Long shackle version prevents thin things from releasing earlier.
Ice cube size is around 30x30x25mm
Shackle has a 0.2mm clearance on every side to allow assembly.
Perfect for timed release, just make sure they don't have a screwdriver... or put in security screws.
