Update 04/27/20 Universal Mask concept with seal

thingiverse

It seems like you've provided instructions and guidelines for printing and assembling a face mask, specifically focusing on the outer seal. The instructions cover various aspects of the design, including: 1. **Purpose of the filter cap**: It's designed to push the filter material against the mask body, ensuring no air can bypass the filter. Additionally, it protects the filter from being twisted during application. 2. **Outer Seal**: This is a critical component that must be applied and welded with care. The instructions emphasize the importance of proper application, ensuring there are no leaks or damage to the seal. 3. **Coughing/Sneezing**: It's recommended to cough and sneeze into your elbow to prevent leakage from the mask. This is also mentioned as an important habit to maintain while wearing the mask. 4. **Important Instructions**: These instructions highlight the significance of printing with specific settings, including: * Printing at a controlled flowrate * Using infill only (100% infill) * Setting the first layer spot on or slightly lower on purpose * Printing at maximum 60mm/s for sealed surfaces 5. **Materials**: The instructions specify that materials should be capable of withstanding: * 60°C without deformation * Isopropylic Alcohol, Ethanol, and Water * FDA certification (better would be medical and skin contact certification) 6. **Deflector**: This component is designed to snap onto the mask and can be printed on a flat surface without support. Smoothing out the "snap on paths" with a soldering iron helps achieve a tighter fit. 7. **Outer Seal**: The instructions outline how to apply the seal, including: * Welding the V-cuts together * Smoothening out the inner side of the weld * Applying the seal to the mask body
