COVID-19 Mask Snorkel filter adapter by MoPrinter

I’ve could only find industrial P95(same as N95 but oil resistant) but the cartridges were sould out. So I’ve made my own. Here are new cartridges and you can also use it with cut-out filter material.

Pint as is, with very little support like in the picture. Use 70 degrees for your overhangs and keep it .3 away from the model.

There are 2 adapters for inexpensive snorkel masks.
