PCI Storage Tower (PCIST)

This is a design I came up with to store a number of PCIe/PCI/PCIx cards that we have lying around in boxes at work and dearly need a better way to store them.

at the bare minimum you can just print off one of the base plates and stick the cards in those and it will hold them fairly well, full height cards do stick through the base slightly so you will need to add some rubber feet underneath the base.

Should you need more you can use M5 threaded rod to connect together multiple layers or spread them side by side and lock them together using the puzzle pieces on the side of each baseplate.
