Respiratory mask with valve [with Fusion 360 source]

thingiverse

This is based on this design: https://www.thingiverse.com/thing:4225667 which I reverse engineered here: https://www.thingiverse.com/thing:4273395 There are three breathing mask sizes (large, medium, small) each one coming in two thicknesses (thin 0.8mm, wide 1.2mm). Two types of filter holders exist: - A standard holder for a sheet of filter which you can buy or make on your own from a surgical mask or a vacuum cleaner bag - An N95 filter holder with a threaded cap I've designed also a belt latch and a filter box container, providing source files for these too. For border sealing use some adhesive seal foam tape. To seal the filter connector, use a bit of super glue. The valve membrane was recycled from an old mask but you can print the one included here or make one on your own with preferred material that has to be flexible and durable. Use the membrane stencil to cut a disk of the correct diameter. You can use the Fusion 360 source file to change the mask thickness and the clearance of all attachment parts. ##Updates *** 10 May 2020 - Recreated the Fusion 360 design with better and cleaner construction for all components - Added all mask sizes - Added thin (0.8mm) and wide thickness (1.2mm) for all mask sizes - Reverse engineered all missing parts: filter cap, N95 connector, N95 cap, N95 holder - Redesigned the valve increasing the membrane holder margin, improving the latch profile, making the base of the cylinder in the cover planar with the base - Created a belt latch
