@XenoCow have you thought about generating the STL files via code so they can be parametric (input height of largest item to stash and it calculates the appropriate angles for you to keep the front of the laptop on the desk and could even give a 3rd/4th point of support by suggesting mid-sized drawers to go along with the big boys)?
Check out the video describing the how and why of a parametric keyboard here, GitHub - adereth/dactyl-keyboard: Parameterized ergonomic keyboard
Oh BTW, I also love this idea for the additional airflow it can provide under the laptop. I have had the “joy” (scorched lap) of having bottom vented laptops and when I’m away from home and the vented laptop stand that has a fan built in (but is too bulky to tuck into my bag) I use these little guys to prop up the laptop when working on a desk.
