Bent-OCD Easy Bento box power mod

Wanted to hard-wire some bento-boxes with minimal effort so I bought some kits from voxelpla but my OCD couldn't stand the messy wire look or the power block flopping around in the back of the machine so I came up with a quick mount that would make this install look like it came from the factory.
