A couple of co-workers of mine had issues storing laptops they use for running tech classes and this is the solution I came up with. There are quite a few of these laptop holders out there but this is (I believe) the first to hold a MacBook Pro specifically and the first that holds more than one. This is incredibly useful for anyone in a classroom setting with more than one computer. It can be used for other computers of similar sizes and should hold them alright but I have only tested it with MacBook Pro laptops.
You have a few options for what parts to print. Two of the "front" parts have numbers on them so that you can organize different devices if need be. If not you can actually get away with print just a bunch of the "back" pieces (two for each set of 5 computers) and it will work no problem and you'll have a faster print.
This was entirely designed in Fusion 360.
