This is a stand for the MacBook Pro 13 inch (it can be scaled up to other sizes) so you can store your Macbook in a small space.
You can also add a bit of velvet to soften the stand for the MacBook and it also looks nice. I also sanded it and sprayed it black for a clean finish, but it's not necessary.
It can be printed with 0 infill and without support while standing up.
It can be printed with any layer height.
