A Raspberry PI stacker, based on K.I.S.S (Keep it Simply, Stupid). Not a real case, but useful to make a cluster.

None of the other solutions worked for me. I have tried Raspberry Pi Nylon Locking Post / Spacer but they are difficult to remove when trying to add or replace Raspberry boards. This is my very first project, so don't expect a high quality design. First time using Sketchup.

I hope you find it useful.

Edit:

Yes, It works for any Raspberry PI board.

No. Mayonnaise is not an instrument.
