Orange Pi Zero Plus Stack Mounting System

Oh, hello! This thing is intended to satisfy a need I had to organize and mount multiple Orange Pi Zero Plus boards in a cluster. I had the boards arranged vertically using board standoffs, but that was very clumsy and I wanted a better solution.

This is my first ever design, so I would welcome any feedback. I have not yet printed this, but intend to do so soon, and will update this thing with any discoveries I make during the printing process.

This thing was designed using OpenSCAD and the source code is maintained here:

Thanks!
