IMPORTANT: BEFORE USING PLEASE REVIEW THE INSTRUCTIONS: https://docs.google.com/document/d/e/2PACX-1vQonfpg9FFtbNixclpxAXkRZ0jRKFbqzUfR5KUAXnKj8JipOlxHbebVlhqzHm8mjrV2OQkctwKMhBVw/pub THIS IS LAST RESORT DEVICE, NOT INTENDED TO REPLACE REGULAR PPE OR AN N95 RESPIRATOR MASK. I MAKE NO CLAIMS OR GUARANTEES THAT THIS WILL PROTECT FROM COVID-19 OR ANY OTHER DISEASE. UPDATE 4/12: Filters and screw cap remixed for better ergonomics (https://www.tinkercad.com/things/hetqbotL8Yw-mask-filters-and-screw-cap) UPDATE 4/5: DO NOT use a repurposed HEPA Vacuum cleaner bag/filter in these masks. Some products contain fiberglass, which can be fatal if inhaled. UPDATE 4/4: Wrote the 3D_Printed_Mask_Instructions.pdf file UPDATE 4/3: Increased structural integrity by beveling bracket around threaded section on mask and refined screw threads. I also included a Cura .3mf build file for the mask only with support blockers already in place. After playing with this design, if you add the Makeup Remover pad as a filter, sandwich it between two "Interior Filter Holder Grid" Grates (like an oreo) for a better fit. I remixed the Montana Covid19 mask to include the screw-on attachment from the Copper3d Mask. This way, one can use as a temporary filter Organic Cotton Round Makeup Remover Pads available at any drugstore. It has been suggested to cut filters out of a HEPA certified vacuum cleaner bag/filter, however I have not tested this alternate configuration. If you wear this on your face, I would recommend frequently washing it in warm soapy water. CAD: https://www.tinkercad.com/things/8DUf9LqWUjQ-hybrid-montana-copper3d-covid-mask I've just printed this mask in PLA and it fits pretty well, however I would suggest printing the mask with a flexible filament to ensure a snug fit. Also, if you want something "custom" fit, you can always pour boiling water in a bowl and set the back portion of the mask (non-filter side) in the water till it becomes slightly malleable- BE CAREFUL THE PLASTIC WILL BE HOT AND IT COULD BURN YOU!
