HensNest

The HensNest About the Design The HensNest was created to address some of the most 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 v1.0 We 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 updates related to the wireframe design and all of the release notes listed below. 1. ASSEMBLY: Assembly for The HensNest is similar to the DIY Face Mask by Mark Fuller and involves first securing the disposable filter within the wireframe. Rubber bands or elastic straps should be connected at the four tabs on the wireframe to create two continuous loops around the head, similar to a disposable N95 mask design. We will release detailed assembly instructions and an assembly video very shortly. 2. STERILIZATION: The HensNest was designed with the intention of having a disposable filter (more on that in a sec) and a reusable wireframe. We recommend printing the wireframe in ABS to allow for both heavy disinfectant use and steam sterilization via hospital sterilizer or home dishwasher. If you’re printing in PLA/PETG, recognize that it will likely not be tolerant to steam sterilization but shoul
