GrabCAD
Based on the Foldable Notebook Stand By Nicuz (Thingiverse), I've redesigned this stand which is foldable to decrease material usage and final height, adjustable (3 positions 7°, 20° and 30°), printable part by part.
It takes 5 hours and 50 minutes on Ender 3 Pro with standard quality.
Needed supports and do not need raft or brim.
No need for screws or nuts.
