If you happen to have 4, 8, 12 or more Intel Galileo devices you can assemble them into a big tower. This design allows you to see all the boards and blinking lights while holding them tightly together. All of the network cables and power goes thru the center of the tower so you get a clean view of the boards and excellent cable management. You can then use Meshcentral.com to remotely manage all of the devices over the Internet and use Arduino Mesh management tools to push sketches easily. Included a part file will print 6 corner parts in one pass, another file with 4 top parts and the STL and Blender files. Video: https://www.youtube.com/watch?v=dQMKWrHOg4k. The original tower at 16 Intel Galileo devices, but we now added 3 more layers for 28. Also, I can confirm that this same part will work with the Galileo 2. The Galileo 2 is longer but the same width, so as long as you have all the same boards of the same type, you just get a different size tower.
We looked at many different ways to arrange Intel Galileo devices into a big arranged array. Because of how the power and network connectors are arranged there is no good way to line them up. The best way we found it to form them into a circle of 4 and stack them. It also looks nice and manages the cables very well.
I provided files for 6 corner parts and another file with 4 top parts. On the Replicator 2X that we have at 40% file it took about 9 hours to print the 6 parts file at medium quality.
