Replacement filter for vented masks

This is a filter that replaces the vent in those vented masks, with a container that can hold a cotton makeup remover pad or other filtering material to help reduce unfiltered outgoing breath. Does it work for Covid-19? I have no way of testing that, but if you do, let me know if it works better than the non-filtering vents.

If you leave your mask in the car, don't print with PLA, it will melt.

Still room for improvement, but it seems to work fairly well.
