Face shield

I enhanced the existing mass printing face shield design by incorporating a slotted hole to secure the screen. The improved design offers numerous benefits: No extra assembly or fiddling required, rapid printing capabilities, and the teeth hold the screen firmly in place within the gap. Pressure from the fastening tightens the screen. Simply insert the screen into the shield and attach the rubber band for the securing mechanism. The rubber band pushes points A towards each other, locking the outer protection of the screen tighter at points B. I provided a figure illustrating the pressure direction. I clearly outlined the dimensions of the model, which can be easily modified if needed. I tested the face shield with a 100-micron screen and anticipate that a 200-micron screen will fit even more securely. I am eager to address any related comments and explore further improvements to my design for a healthier world. Let's work together to create a safer environment. UPDATES: I added two new models for the A4 landscape version of the face shield, one with hooks and another with small holes in the bow.
