A 3d printable gas mask filter using 40mm NATO threads. The mask's dimensions were designed for a fabric, activated charcoal, multi purpose fiber slot, and another mask slot. The slim tube is meant for the wrap around mask I will release nextTo assemble the filter... take a surgical mask or piece of cloth and drop it down the tube, then fill it with 4"s worth of activated charcoal (Can be made with a campfire and a high or low PH liquid such as bleach or lemon), then add another 4" worth of a specific chemical counter or a HEPA style lattice such as fine fiberglass shavings (Can be acquired online or from the inside of a HEPA filter), than finish with another mask. Disclaimer if you use fiber glass shavings you need to confine it to the tube or inhaling it will cause serious problems.
