12V Heatbed Relay Box

Update: Don't directly plug that model relay into the Ramps D8 port. After being energized for about three seconds, it emits a loud, gunshot-like sound and shoots brown fuzzy material everywhere. ------------------------------------------- This box houses a Prusa i3 printer heatbed relay. Most don't need an external relay, but in some cases connecting the heatbed directly to the power supply works better. The bottom of this box features offsets that allow the solder connections on the relay board's underside to hang, ensuring the board lies flat. The cover doesn't snap into place. I didn't have enough patience to add screw holes through the bottom and create a snap-in-place cover, so I've included a Sketchup file for modifications.
