Fan grid with filter insert for 2-inch hole

This is a cover for a 2-inch hole that has a cooling fan on the other side. There are two parts to this thing: A screen and a base. The two parts are crazy-glued together. Before crazy-gluing, insert screws in the base. There is access to the screws from the screen itself.

There is a slot/opening for the insertion of a filter mesh. My filter is about 0.15-inches thick.

I usually have to scale by 10 all my drawings when they go into my slicer. It maybe because I draw them in mm and slicer
