About this 3D model
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
