Face shield modified

thingiverse

I modified the existing mass printing face shield by adding a slotted hole to accommodate the screen. The new design boasts several benefits: - No additional assembly or tinkering required - Fast printing capabilities - The teeth securely hold the screen in place, fitting snugly into the gap - The screen is tightened firmly by the pressure of the fastening To assemble, simply insert the screen into the shield and secure it with a rubber band. As the rubber band applies pressure, the points A are pushed together, causing the outer protection to lock the screen firmly in place at points B. Refer to the figure "pressure direction" for clarification. I included detailed dimensions for the model, which can be easily adjusted if necessary. I have personally tested the face shield with a 100-micron screen and found it to fit seamlessly. A 200-micron screen should fit even more securely. If you have any related comments or suggestions, I'd be happy to respond and explore ways to further improve my design. Let's work together to create a healthier world! I've attached the STL file with the updated design featuring a slotted hole. Updates: I've added two new models for landscape versions of the A4 screen: one with hooks and another with small holes in the bow.
