Mega Zero Heated Bed Project

I wanted to add a Heated Bed to my Zero but didn't want to switch out the PSU or build platform. I decided on a 110Volt Heated bed and a Solid State Relay to trigger it from the stock board or SKR Mini MZ. This works very well on the stock PSU. I designed this case to house all the components as well. Willnewton's Cover was nice to start with for the cutouts and look I was going for on top. I screwed the SSR to the lid as I was afraid the clips alone would not hold if it got warm. The Bed temperature drop is roughly 5 degrees Celsius from center to far corner.
