This is not our design. Its meerly a print service of a free file from https://www.coronavirusmakers.org/ We are just offering this as a service for those with no printers who want this style. You will have to supply your own straps and filter. You can easily make a 98% effect filter from a HEPA furnace filter. One furnace filter will make many mask filters. Use 2 layers for best results.
Printed in Black PLA. You will have to glue it together yourself and provide you own straps and filters. This is meerly a print service of the https://www.thingiverse.com/Spazticus/about designs. He gets full credit, we are simply charging print time and filament.
This 3D model has not been approved by any regulatory agency and has not passed any laboratory tests. It is a prototype designed by LAFACTORIA3D (a Spain-based company), presented among many other works in the CORONAVIRUSMAKERS community, created with the aim of providing emergency protective material to medical professionals who need it, given the current global shortage of supplies. It is not intended to replace any homologated mask, but to provide minimal protection. We cannot guarantee its operation, so use it at your own risk.
Please, read the assembly instructions, as well as important security information:
NOTE: contains LaFactoria3D's original mask parts that this is designed to fit. It's a good design, but if you feel their updated version provides better protection I urge you to use it instead.
Replacement cap for LaFactoria3D's COVID-19 MASK
While printing mask parts for Lowell Makes I wanted to find some way to help healthcare workers relieve some stress. Making replaceable caps seems the best way to offer an adjustment; these clip right onto existing masks without interfering with function and maybe they can lighten the mood in pediatrics.
This is my third model: the Optimus Prime version. It clips in place of the existing cap, is lightweight, doesn't interfere with airflow, and might fit under a face shield. Version 1 of this is included (the solid piece) in case that's better for your particular printer.
The sides and mounting bracket can be printed without supports, but the front and top still need some. I would experiment with them at different angles; tipping the top piece forward around 60 degrees reduces the supports to nearly nil while eliminating any stepping pattern that would normally occur on the near-planar surfaces. Then simply glue the mask front and top together, add the sides, and lastly glue in the mounting bracket so you can test fit the connection. Hit me up if you have Peter Cullen's contact info so I can send him a painted and fully assembled version. [joking/not joking]

If you find any issues with it or think of ways to improve its design, please let me know. Feel free to modify this and share it to the community.
