PC case air intake filter box (80×140mm)

Long ago I notice a trouble on my computer case: it has a slot for a fan behind a facade that had almost no hole to let air flow through it! Quite a lamentable design flaw! A second and common trouble is the dust accumulation into the computer. My answer to this two troubles is to open the facade to make an air intake with a filter into a box behind it and a gird in front of it. Additional hardware: - 4 M4 nuts, - 4 M4×10mm screw, - air filter. The nuts are to be inserted into "boite.obj" which is to be placed inside the case. The "gabari.*" files have two goals: - help drilling the holes: the air intake's one and screws' ones, - help cutting the air filter. The air filter I buy is too dense, so I had to slice it. If you know where to buy good ones, let me know into the comments. To open the box, just unscrew 2 of the 3 screws that keep the front gird in place and just a little the 3rd one. Them turn the gird, the box is still keep in place by 2 screws that is enough to keep it in place so you can screw the other back up.
