Clamshell Macbook stand

Vertical stand for macbook in clamshell mode.

Update April 8 2021, I added a 2mm chamfer to the top edges of the stand and included the .step file.

I made this specifically for my Macbook pro 13' 2015, but it's still compatible with all models from 2012 - 2015 with same dimension; The gap is around 18mm wide, perfectly for my laptop.
I recommend adding some rubber pad to protect your laptop.
