Gas Mask

NOTE: This is a preliminary design, that still needs testing and refinement. DO NOT WEAR THIS VERSION!

This is a 3d printable gas mask design. It's printed in 3 parts - the main mask, the canister, and a gasket to hold the face shield in. The face shield is cut from a piece of clear plastic.

The filter material is activated charcoal - you can buy this at any pet store. Put a layer of cotton batting in the bottom of the canister, then fill with activated charcoal, then put another layer of cotton on top, and screw the canister into the mask.
