My local microcenter sells the Pi Zero for $5 so I grab one every time I order something. I have quite a few of these and wanted to group a few together and get going. This is one of those cases where you can say someone designed it, then shipped it to one of those laser cut locations to make a ton, and then boxed it up to sell at Revain. There's nothing wrong with that, but I believe anyone can do it. It's pretty easy, you just glue 3 Pi Zeros between 7 layers of acrylic and screw it in. I'm a bit concerned about cooling, but I'll admit my Stack 3 Pi has been sitting on my desk for months without even plugging it in, so I have no idea if this is a legitimate issue. Overall this is a good way to have a 3 Pi Zero Kubernetes cluster if you want to play around with something like this.
