Thanks to everyone who accepted the challenge to help our health care workers! If you would like to deliver these to these to our health care friends but don't want to get too close to a hospital, you can make a contactless drop off at our home and we will relay them. Contact us via social media for our address. Please check back as we make improvements to this design and evaluate others!
OUR ASSEMBLY VIDEO:https://www.youtube.com/watch?v=CMtQ2avElZs
ABOUT THIS PROJECT:
We were looking for a way to assist in this health care crisis. One of the problems that were presented was a shortage of N95 masks in hospitals. These were already being rationed.
After some online searching, we found this open-source project:https://copper3d.com/hackthepandemic/https://copper3d.com/pdf/Copper3D_Release2.pdf << DISCLAIMER <<
PROS FOR THIS DESIGN:
Easy to ship flat
Flat design is easy to print
Two layers of filtration
Easy learning curve for thermoforming
Adjustable tension straps
Straps can be immersed in sanitation bath
FURTHER INSPIRATION: Jeremy Simon of 3dUniverse.org made several good videos demonstrating, improving, and analyzing the masks: https://www.youtube.com/watch?v=0QmpnzBvXgk
I also found an improved model with tapered flaps for melting/sealing that I liked very much:https://www.thingiverse.com/thing:4235063
To these I added:
Expanded flat overlap/connector strips to allow for a better seal at the nose bridge and nose base.
Increased reinforcement ridge depth to help hold shape better during thermoforming.
Reinforced filter rings on mask (originally printed very weak on my printer, had some separation of the filter threads on one side.)
Updated filter caps and filter inserts
Mask attach points that do not perforate the mask, therefore pulling the sides in towards the face rather than slightly away.
Tensioner clips for easy tightening and release.
Straps are made of this:https://www.amazon.com/Pepperell-Pony-Bead-Lacing-Black/dp/B001N9TCMO
Weather stripping:https://www.amazon.com/Duck-Heavy-Duty-Adhesive-Weatherstrip-282433/dp/B0025KUSXW/
