12V Heatbed Relay Box

Update: Do not plug that model relay (shown) directly into the Ramps D8 port. After being energized for about 3 seconds, it makes a sound not unlike gunfire and shoots some kind of brown fuzzy stuff all over.

Box for a Prusa i3 printer heatbed relay. Most don't require an external relay but in some instances, connecting the heatbed directly to the power supply works better.

The bottom of the box has offsets to allow the solder connections on the bottom of the relay board to hang so the board lays flat.

The cover doesn't snap down. I didn't have enough patience to add screw holes through the bottom and snap-in-place cover so the Sketchup file is included for modifications.
