I designed this laptop stand/holder so that I can store my laptops when not in use.

The laptops stay at an angle (adjustable, also can be set to zero) so that I can pull one out easily. The angle of the stand in the picture (and stl) is at 1.5 deg, and is enough, I don't recommend more.

In the Fusion 360 version, you can change almost everything (except fillets) using “Change Parameters” command. (After changing params, please measure (with “i”) to see if the base where the laptop stays still fits - using angles lowers it a bit than what you put in params)

Printing:

I recommend using a modifier like in the picture with 100% infill. Also 100% infill at the bottom for 5mm would add some heft to it.

But really, you can print any way you would like.
