This is a Microsoft Surface Book (13") laptop stand. The angle is 30 degrees.

I struggled to find a stand that fits my surface book well, the laptop is back heavy. Some are too small, others are too big for my printer. I ended up creating this, my first design.

Dimension: Laptop surface angled face sits 222mm, length 216mm, raised height 136mm.

Bridge width: 235mm.

Printed on my Ender 3 Pro with PLA, need to set skirt off and rotate slightly to fit within the printable area.
