Find the design on Printables: Wedge Laptop-stand by impulse1delta
The chassis/case is definitely not designed for that kind of load for extended periods of time.
Especially when it’s running hot… extended heat and bending forces just makes me nervous.
I love the concept though and doing something like this on the back hinge in a scenario where it’s docked but allowing it to be slight open like a clamshell would be cool.
You could more easily vent the heat, the “back” the laptop is pretty resilient as long as you’re sharing the weight with the bottom and top (not just the hinges)
