Thanks! Yeah, I actually did have to fire up the 3D printer for this project too. That was when I realized I the control box I bought was too small for everything that needed to go inside…oops. So I made the funky blue extension for the connectors which can be seen in the photos to get the stiff stems out of the way from the box interior.
I would bet that 5 years ago, my garage was a lot like yours. It has definitely been a process. I previously posted a short shop tour in another thread, since you asked. And it actually references the need to make these blast gates, lol — full circle.
