Face Mask - Respirator with filter

thingiverse

The face model used comes from:https://grabcad.com/library/male-face. Compared to other available face mask designs, this one fits the common face profile better and provides a tighter seal. Bigger strap loops have been included, as well as a provision for placing the filter in the cover instead of the mask itself, allowing for quicker changes without needing to remove the mask. The cover can be removed by rotating it 25 degrees either way, and secured just as easily or with a press fit when not in use. Please share your thoughts and feedback on this design. Feel free to make any necessary adjustments and print it if you have access to a printer - note that scaling down to 0.1 of the STL files may be required. Your input is appreciated, especially regarding potential tweaks to the design or analysis methods for CFD. The primary goal is to compare efficiency and user experience with existing designs, considering factors like filter type, seal quality, and other variables that affect breathing effort and fatigue. Any suggestions on these fronts are welcome. As always, this CAD design has not been tested or approved by any medical organization.
