I was looking for a clean solution to stack different single board computers. I found this existing design for Raspberry Pi's. This existing design can also hold an OrangePi 5, but I created other versions for other types of single-board computers:

• OrangePi RV2 (RISC-V)

• LattePanda IOTA

To further improve the stack, I created this extra nameplate to hold a Dymo label to identify each board in the stack.
