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

thingiverse

I attached the mask with built-in adapters for 3M canisters at a Medium size of 100% or a Larger size of 108%. Print the mask, the thin and thicker gaskets made of TPU, and choose your preferred canister. I recommend using the one linked below for excellent airflow. ***************************************** If you're using existing masks from my previous version... https://www.thingiverse.com/thing:4242190 Print the Geminus Mask in Medium or 115%. Then print the TPU mask gasket in Medium or 115%. Next, visit https://www.thingiverse.com/thing:4160375 and print two of each: the filter, the mount, and the star. No size adjustments are needed. From this post, print two Med or 115% lugs at a 35 to 50% infill setting. The lugs will fit tightly into the mask holes, so sand them until they push in but not loose and flush with the outer edge. Once you've prepared the lugs, epoxy the mask and install the lugs to seal them in place. The gaskets will fit either size, and other 3M replacement filters will also fit on the lugs. The two sizes of gaskets have been designed to fit most masks that use a 3M 6000 filter. When the epoxy is completely dry, assemble the mask with the TPU mask gasket, apply a lug gasket, and try whichever 3M replacement filter design you prefer.
