Test fit looking at oddball corner. Prior slider plate I had had no mount from the slider to the compressor here. Reason is obvious. I could have skipped it too in this plate remake but think there’s just enough space to make a 4th bolt work. Jam nut here is certainly not optimal but better with a bolt & jam compared to no bolt at all. Will get rid of the powdercoat where the jam nut seats. Blue lock it. If necessary, can hog off a bit of flange or bracket material. Thin wavy? Bolt shaft = 40mm. Spacer = 3/8". Bracket = 1/2" thick.

I have been using QCad Pro ($38) because it's Apple Mac native and pretty easy to use for 2D only. A couple youtube videos about how to use and you will be off and running.

You do however need some pretty good graphic processing power.

I use both sketchup on my Mac and shapr3d on my iPad Pro. Both have their pros and cons- shapr3d is super intuitive and easy to use but neither are as powerful as fusion360 but conversely shapr3d took almost no time to learn.
