HensNest v3 · 模型 195229
The HensNest v3 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 v3.0 The v3.0 HensNest design represents the final tweaking of this design pathway. 1. DESIGN MODIFICATIONS: HensNest v3.0 features two important design improvements from v2.0, namely, (a) a separate Strap Hoop to make attaching straps much easier over the bulky filter material; and (b) a more articulated Containment Hoop to improve assembly and containment. 2. SECUREMENT STRAPS: Straps can now be looped directly through the buckle feature on the Strap Hoop for easier securement. This can be done in either an ear loop fashion or a behind the head manner. The Strap Hoop also now engages bumps in the X-Ribs for secure snap fit assembly. This design change makes changing filters easier, by reducing the number of steps, and allowing for better adjustment. https://me.udel.edu/hensnest-3d-printed-face-mask/ Release Notes for v2.0 The v2.0 HensNest design is production ready and includes complete assembly instructions. We are continuing to make minor tweaks to the design and will update these release notes as we progress. 1. DESIGN MODIFICATIONS: HensNest v2.0 features two important design improvements from v1.0, namely, (a) an interior retaining ring that secures the filter in place; and (b) ergonomic improvements to the lofted wireframe to fit more comfortably around the nose while holding the filter material further from the face. 2. FILTER MATERIAL: We have been experimenting with several commonly available filter materials, and our current recommendation is to use one ply of a (clean!) furnace filter. We recommend higher performance filter...
