We've heard that face masks cause chafing/abrasiveness behind the ears for anyone wearing them for an extended amount of time. There has been a a lot open source designs that are 3D printed, and while great they take WAY too long. These should really be die-cut for scale. But while that comes into play, we have a laser cut in the meantime...so lets go! it's much faster.
V1 is mostly built with all the open source projects out there. The rough size, shape.
Things we've observed...
If you are unable to make a bun or pony tail with your hair...the design sits a little too low. Instead of it being abrasive on the back of the ear, there is now a constant pressure on the top of the ear. This will get adjusted with future versions. The hooking mechanism is just not angled enough.
If the ear relief is designed well and nested well, most face shield manufactures SHOULD be able to get yield without additional material cost on a sheet of 4x8 raw stock. Just processing cost which should be low.
Material PETG 0.020 ot 0.030 will both work.
