3M 7500 Series Mask Exhaust Filter

We found the original filter area was hard to breathe through when using filter paper.

Used OPs design as reference for this new object.

Increased output area to 70mm x 70 mm square.

Added larger grill with clips to hold it in place.

Prints fine at .2mm.

With good bed adhesion, no skirt or brim required.
