9-Volt Battery Cap

This is a simple plastic cap designed to protect 9-volt batteries from shorting out and starting fires while in storage. Keeping unprotected 9v batteries in drawers or containers with other batteries and metal can be very dangerous. When everything gets jumbled around, it is possible for a piece of metal to short the terminals of the battery, which will make the battery overheat and catch on fire. This is a common cause in house fires.

The cap simply snaps onto the terminals of the battery and protects it from short circuiting. I printed mine on a Replicator 2 with PLA @ 0.2mm layer height. It snaps into place perfectly and takes 5 minutes to print.
