Make your own custom Montana Mask with pleated filter!

If you are unsure which files to download read the READ ME.txt This design enables makers to 3D print custom-fit reusable face masks. In addition to print files, there is a guided video showing how to make a face mask that fits your face perfectly. Using free software and open-source plugins, you can create your own custom face mask model in under 20 minutes. This project involves the use of multiple open source projects: 3D WASP, Facebuilder, and The Montana Mask. 3D WASP has developed an open-source add-on for Blender that adapts a mask from a face model. Facebuilder allows users to create a 3D model of their face from photos. By combining the two programs, WASP and FaceBuilder, with free software Blender, you can create your custom mask. This is the easiest method I found and led me to create this guide so anyone can do it. More info on the add-ons used and The Montana Mask: https://keentools.io/facebuilder, https://www.3dwasp.com/en/3d-printed-mask-from-3d-scanning/, https://www.makethemasks.com/about-the-mask My addition is a pleated filter design for The Montana Mask. I created a pleated filter that provides more surface area for filtering out particles, making it more efficient and effective. The CDC has issued guidance on homemade face coverings, stating they provide an initial barrier to aerosolize droplets. Further, wearing a face mask acts as a deterrent to touching your face. This recommendation is intended to help preserve proper masks, which are in short supply due to the nationwide shortage of personal protective equipment. According to scientific data from China, 56 degrees Celsius for 30 minutes is enough to neutralize COVID-19. To be safe, you can place the mask in a preheated oven at 65 degrees Celsius for 35 minutes. Standard disinfectant wipes may also be effective based on findings by Make The Masks. There were concerns that PLA could be porous and therefore wouldn't make a suitable mask material. However, tests conducted by Make The Masks found no bacteria growth after cleaning the mask with hospital-grade bleach wipes and Sani-wipe.

There are many options available, and I recommend a weather seal or gasket. You can also shape the mask slightly after printing using hot water. Place the face end of the mask in water that is 60-70 degrees Celsius for a few moments and then remove and dry completely before pressing onto your face (Repeat until happy). Remember to be extremely careful when dealing with hot water, and do not put hot plastic on your face. Please remember this is an open-source research project. I highly encourage you to remix this prototype design and create your variations. I look forward to seeing your remixes!
