No-Hardware Parallella cluster. It is meant to make an 8-board cluster. With the large heatsinks, passive cooling should be perfectly fine, however a fan to blow through it might help.

THIS IS A LARGE PRINT. Unfortunately it is a rather large print, so to account for that, print the legless version and two 'tentacles' and attach by some method such as friction welding (https://www.youtube.com/watch?v=wghk6K7UgbM).

Check out a different version that does require hardware, but is smaller.
