I recently released a stand I made for my ThinkPad Yoga. It'd probably work for a Macbook too. They're very close in size. I like mine a little better because I can put the dock and cables under it. https://github.com/KeenRivals/ThinkPad-Yoga-Laptop-Stand
Nice, thank you for sharing! I'm curious, which 3D printer did you use?
It would be difficult, and inadvisable to print something this large on a regular 3D printer.
Thingyverse is literally full of designs like this and often much better.
