Suggest to print in PLA, it will work with PETG, bu PLA would give you the best result and PETG is not necessary in its intended use. This is designed for 7500, it should filter out or contain virus that you might have and stop it from spreading to others. A normal mask could be cut in to at least 12-16 circle pieces. It will work with 2 layers of mask in each filter, but best to keep it single layer for a good flow of air into the Mask. Note: you might want to use a knife to trip the top of the Screw head to make it easier to screw into the cap, but it is not necessary. If you find that this does not provide protection to the filter as it is exposed, I have other 3 designs uploading with shield directly in front, but those will require support.
