I wanted a nice thick side cover, and thick reinforcement of the grille so I made some changes to the base model.

I thickened the grille by about 1mm, so it's about 6mm thick. I made it compatible with M3 SCHS screws since I kept breaking plastic tabs off of my other one (I used 10mm, but a wide range of lengths would work) and M3 (4.2mm OD) threaded inserts (the threaded inserts need to be put into the fan itself).

Recommended to print in ABS/ASA or better.
