I made a simple modification to the original middle section of the yooodaha's design. I wanted to use standard 25mm+6mm standoffs, so I recessed the holes a bit, so the standoffs could screw into the standoff below it.

This thing is just the middle section. You can use this with the original top and bottom sections, or I just used the middle sections for all of them, as I like the increased air flow of the middle section.

Use thecart from the original design

It's best to assemble this from the bottom to the top.

I used the following hardware:

M4 25mm + 6mm standoffs (just search for this on amazon)
M4x6mm screws for the top.
M3x4mm screws to attach raspberry pi to cart.
M4 nuts for the bottom.
