This is a Remix of PerezLP's fantastic design, I just customised to my personal needs.

The widh of the gaps are ~19 & ~22 mm. The wider gap was modeled to hold the round hinge of the Microsoft Surface Book 1 & 2 while keeping it shut. Anybody using an upright stand might know that the books love to open when held upright.

The smaller gap is for the Microsoft Surface Pro (in my case: 7, but it will hold any Surface Pro.

I am aware this a VERY specialised remix, but I was meaning to do that for quite some time now.

Print with variable Layer hight and Tree support structures of your choice.

Enjoy
