About this 3D model

An adapter for adding a filter to a snorkel mask easily found on Amazon. I printed this so that I'd have something when I go to the store, since I've read a lot about cloth masks being ineffective. I don't know that this is necessarily better, but I imagine with the right filter material it would be, since it's airtight.
