This is a laptop stand designed to hold a 14" machine, up to 24mm (roughly 1in) thickness. I've tested it mostly with Lenovo's T14 g4/5, E14 g5/6, or dell 7450 notebooks. The base is 130x130mm, total height 96mm. Using 20% infill, total print weight is about 100-105g. 

Print settings:
PETG, infill 20%, at least 3 horiziontal solid layers depending on layer thickness and extrusion width. You want the vertical pieces to be almost solid, to hold good strength and best stability.

Post processing:
If needed, heat up the top parts with a heat gun and adjust them slightly to hold the notebook more securely.
