MCCM2 Compact Gas Filter

grabcad

3d printable compact gas mask filter using 40mm NATO threads. Utilizing the same easily manufacturable stack of the MCCM1 but divided between two chambers, halving the intake and lifetime of the filter's contents. To assemble the filter... read the MCCM1's description; I'm not writing it out twice. The smaller filter will be about 10% harder to breathe through the same stack in the full size, but last half as long, yet with the same filtration power. In my opinion the compact version is a vast improvement on the bulkiness of the mask and unbalanced weight on the users neck. In exchange for carrying an extra around with you.
