This project arose from the need to package 32 Raspberry Pi boards to construct a Raspberry Pi cluster for my daughter’s science fair project. She came up with the idea of arranging 16 boards on a circular acrylic plate and stacking them up. The stack was then placed on an acrylic stand with a shelf to place an Ethernet switch and power supply. The entire package was designed using Autodesk Inventor and fabricated using acrylic sheets. The cluster is now fully operational. Project Link
