Freezer Power Loss Indicator
by Brett, published
I travel a lot - and wanted to build something to replace my bowl of ice cubes that was my previous freezer power failure indicator.
I made this on sketchup and it does the trick nicely.
Print the lid and base.
Install the lid on to the base and put an ice cube in the lid so it's held above the base by the lid's open floor.
Should power fail - the ice cube will melt and the water will drain into the lower container, possibly refreezing should power be restored.
My lid and base fit together snugly with a little bit of english.
