Respiratory mask with valve [with Fusion 360 source]

Description

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 3 breathing mask sizes (large, medium, small) each one comes in 2 thickness (thin 0.8mm, wide 1.2mm). There are 2 types of filter holders: - A standard holder for a sheet of filter (you can buy some filters or make one on your own from a surgical mask or from a vacuum cleaner bag) - A N95 filter holder with a threaded cap I've designed also a belt latch and a filter box container. I've provided source files for these too. For border sealing you can use some adhesive seal foam tape. To seal the filter connector, you can use a bit of super glue. I recycled the valve membrane from an old mask, but you can print the one included here or make one on your own with the material you prefer. It has to be flexible and durable. You can 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 the attachment parts. ##Updates *** *10 May 2020* - Recreated the Fusion 360 design with a 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 the 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 ***
