Filter Adapter for COVID-19 Mask v2

***PARTS ARE IN INCH UNITS*** -> You'll have to tell your slicer this or they will be wrong (obviously). If you don't have a way to do this you actually probably do. Otherwise, scale factors to other units (like mm) can be found by doing a simple Google search. This in an educational lesson in unit conversion and part scaling. *UPDATE 4/12/20:* I uploaded a new 'cap' file which has tighter compression for thinner filters. This is a filter adapter for v2 of the COVID-19 mask by lafactoria3d: https://www.thingiverse.com/thing:4225667 I thought the filter area was a bit small but I still wanted to use their mask parts due to the good design. I designed these parts to screw onto their N95 connector plate and allow for a 2.5" filter disk out of whatever material you want. The parts are designed to clamp around the outside of the filter disk to provide a good seal. More to come later. I don't have a good filter material to use with this so I'll have to test that later in the week. I'm also trying 'foam backer rod' as a face seal for the mask and will post details on that if it works. None of the parts need support although you'll have to reorient them on the print bed to have the logical side down. The threads can sometimes be tight so if you find this to be the case just work them back and forth, little by little, and they will wear in (this takes about 30 seconds). Don't just force the parts together the first time or they could get jammed together.
