The HensNestAbout the DesignThe HensNest was created to tackle some pressing issues with current face mask hacks. It was inspired by both The NanoHack by Copper3D and the DIY Face Mask by Mark Fuller. The HensNest has a flexible printed hoop frame that conforms to the face without post-processing steps, like using a heat gun or applying a sealant. The filter surface area is very large, addressing issues with the breathability of hard-sided mask designs with small filter towers, like The NanoHack. The HensNest adds a tented structure to the design that keeps the filter surface away from the mouth and nose, which we learned from our clinical collaborators is critical for keeping the filter dry and functional during extensive use. Lastly, this design is mostly planar and is fast and cheap to print. If you have design improvement suggestions, please post to the comments section below.Release Notes for v1.0We released HensNest v1.0 to give the maker community a chance to further “hack” our improved wireframe design. We will continuously release design improvements and manufacturing notes in a good faith effort by all parties to help with the COVID-19 pandemic. If you use, copy or share this Item, you agree to utilize these files for production of masks at your own risk and comply with any state and federal guidelines for use of these devices. some design questions we received: 1. What keeps the filter media in place/taught around the perimeter? Will this sag/make contact with the face, re: wicking/saturation? 2. The tabs that connect the frames appear to protrude beyond the plane that makes contact with the face...is this a comfort or seal issue? 3. What is the filter media? 4. Intended strap material? Keeping in mind it's a work in progress, with nearly as many questions, as answers.. 1) Currently nothing keeps the filter media in place/taught around the perimeter. I've played with multiple options, but not settled on one yet. 2) The tabs that connect the frames do protrude beyond the plane that makes contact with the face, which might be a comfort or seal issue. 3) The filter media I was using is taken from a HEPA furnace filter. Without knowing yet whether one layer, or more are needed. 4) The intended strap material is unclear. Design considerations: * Currently nothing keeps the filter media in place/taught around the perimeter. * The tabs that connect the frames do protrude beyond the plane that makes contact with the face. * The filter media is taken from a HEPA furnace filter, without knowing yet whether one layer, or more are needed. * The intended strap material is unclear. Future work: * Investigate options for keeping the filter media in place/taught around the perimeter. * Address the issue of the tabs protruding beyond the plane that makes contact with the face. * Determine if multiple layers of filter media are needed. * Identify a suitable strap material.
