Here’s a laptop lift I made using ProofGrade material. I designed it to not require any glue and to not wiggle at all. That of course means it requires some light tapping with a rubber mallet. I’m able to get rid of my Zoom double chin with the lift this provides! Also, I left plenty of spaces for hiding external storage and wiring.
I’ve been wanting to make one of these, because my laptop also gets blazing when editing and working. Great design, I may finally get around to making one now ( after I get around to making the 10 other things I have on my list )
Be aware that as the ambient temperature and humidity change your joints may come loose or get tight enough to break. I generally prefer to allow a little room and then glue joints to allow movement. This prevents failure due to either overly tight or overly loose joints when your material changes size.
