These are custom mesh screens to go on the inside of the Legion Go Backplate by FSULAUBACH found here. This post is the meshes only.

I wanted a finer mesh on the inside of FSULAUBACH's backplate because the vent holes are a little larger than I'm comfortable with, given the proximity of bare components on the other side. I have not temperature tested my Legion Go with these meshes (I still have to apply the heat inserts and install it on my device), but I expect this to be fine.

I used CA glue to adhere the meshes to the back side of the backplate. Wax paper is a trick to hold down the meshes while the glue cures without gluing your fingers (CA glue typically doesn't stick to wax paper).

Walls: 3
Top/Bottom Layers: 0
Sparse Infill Pattern: Honeycomb
Sparse Infill: 35% (25-35% is about right).

If you do not set your Top/Bottom Layers to 0, you will end up with a solid piece. This is a cheat to get the mesh effect without actually modeling the geometry; I'm lazy, and the trick works fine. If you're feeling lazy as well, you could use my 3mf file (included) instead of fiddling with settings. Just keep in mind my settings work for me, but your mileage may vary.
