3D Printable DIY Filter Mask

thingiverse

A relatively simple 3D printable filter mask with optional, removable front cover to shield droplets. https://youtu.be/oy2zM_xlmvg Edit, or just save as STL: https://a360.co/39rR0vm (CC0 Creative Commons Public Domain - "Freely you have received, freely give." -Matt 10:8) For best results: - Print the face seal with TPU/flexible filament for an airtight seal (test by covering front opening). - Fill in crevices (inherent with filament deposition) to reduce areas bacteria can hide. - Use as effective a filter you can find that is still breathable. - Use an elastic band that will maintain the seal. Benefits: - Customizable front cover for additional protection as well as potential personalization (if you want to do a bit of 3D modelling). - Usable with a variety of filter materials (although this could be a drawback with poor materials). - Few pieces for easier cleaning and printing (Face seal, filter cap, and optional front cover) Drawbacks: - Not certified. - No eye protection. Should be supplemented with, for example, goggles. - Crevices from filament deposition provides areas for bacteria to hide. - May need to tweak the model for a better seal/fit. - May be harder to get a seal if you don't have TPU/flexible filament (e.g. with hot water softening). - Not as easy to clean or fabricate as fabric face masks. - I'm sure there are more.
