Raspberry Pi Stackable Cluster Mount

I needed to slightly adjust this model in TinkerCAD to shrink the pegs as I am using the PoE+ hat, but I liked the minimalist design and style of the original source. I also made the pegs slightly slimmer as I was having an issue getting the Pi 4s I was using onto them without deforming them. I think being small and using PETG just made the tolerances too tight. Hopefully this helps anyone else also using the PoE+ hat and needing shorter pegs.
