I created a stand for my Macbook Air M2 from 2023.
There are 2 versions, 1 with an Apple Logo and 1 without a Logo. I printed for myself the Version without the Apple logo.
I added a little more room because I do use a case with my Macbook.
The slot for the MacBook is 16mm.
Just let me know if you need something changed, I will do my best to get back to you.
