The Shield, Mk IX - First responder shield

thingiverse

For several weeks now, our makerspace has been diligently producing PPE for local doctors and frontline workers. We rapidly fell in love with Joel Telling's "Manta Ray" face shield, as it effectively combined the best features of two NIH-approved models: the Prusa Shield and The 3D Verkstan shield. With nearly 1,000 pieces of PPE printed, the most significant feedback we received from those who had used both of the other shields was that the Manta Ray placed the shield material too close to the user's face, making it more prone to fogging from breath. Following a number of revisions, this shield visor is the final result, and we feel it brings together the best features of all current NIH-approved shield designs. It boasts a curved front and sufficient distance from the face that makes the Prusa shield superior. Additionally, it features a headband that securely holds to the head on its own and doesn't require a band for most users. There are nine files included - Cap file, for making a cap that pressure fits on top of the frame. Visor files, in two categories. Each category has a model with 1, 2, 8, and 12 visors. The two categories are identified by the end of their file name and are as follows: CREALITY: These files are optimized for most Creality machines and others where 0.28 layer heights are optimal for the machine. GENERIC: These files are designed with 0.3 layer heights, making them compatible with a vast majority of printers that utilize a 0.0025 "magic number". And while the shield wasn't specifically designed with the #FaceCoveringChallenge in mind, we encourage you to have fun!
