I'm starting the build with my controller.
I am using an Antec 300 PC case as the enclosure. I am using a latching control circuit with a contactor to turn the ac on and off on the power supply. See #3 here Contactors and Control Circuits
I have a 3d printer (several) and am designing and printing a lot of the components to customize the controller. I am using openscad to design the parts.
The first component I designed was the mount for the breakout board
