Freezer Power Loss Indicator

thingiverse

To replace my bowl of ice cubes as a freezer power failure indicator, I designed and built a device using Sketchup. It's simple yet effective. Print the lid and base, attach the lid to the base with an ice cube held above by the open floor. If power fails, the ice cube melts and drains into the lower container; it may refreeze if power is restored. The lid and base fit snugly together. Give it a try!
