Covid19 Mask (Geminus Dual Filter) with 3M Filter Adapter

thingiverse

I added the mask with the adapters for 3M canisters built right in at a Medium or 100% size and a Larger 108% size. Print the mask, the gaskets (thin and thicker) in TPU and find the canister of your choice. I like the one linked below for great airflow. ***************************************** If using the existing masks from my previous version... https://www.thingiverse.com/thing:4242190 Print the Geminus Mask in Med or 115%. Then print the TPU mask gasket in Med or 115%. Then go to https://www.thingiverse.com/thing:4160375 Print two each of the filter, the mount and the star. (No sizing necessary). From this post, print two of the Med or 115% lug at 35 to 50% infill. The lugs will go into the 2 mask hole VERY tightly. I sand until the lug mounts (prongs out) push in but not loose and flush with the outer edge. At this point I epoxy the mask and with the lugs installed to seal them in place. The gaskets will fit either size. Other 3M replacements will fit on the lugs as well. The 2 sizes of gaskets have fit most designs that fit a 3m 6000 mask. When the epoxy is completely dry, Assemble the mask, tpu mask gasket, put on a lug gasket and try whichever 3M replacement filter design that you want. Assume that this is for show and it is not approved by the CDC, WHO or anyone else who approves masks for use in medical situations.
