Face shield modified

I modified the version of the existing mass printing face shield with a slotted hole for the screen.

The new design benefits:

• no additional assembly or tinkering required
• fast printing
• the teeth hold the screen in the gap
• the screen is tightened by pressure coming from the fastening

Insert the screen into the shield and add the rubber band for the fastening. The rubber band pushes the points A towards each other, and therefore the outer part of the protection locks the screen firmer at points B. See the figure "pressure direction."

I indicated the dimensions of the model, which can be easily changed if necessary. I've tested the face shield with a screen of 100 microns. A 200-micron screen should fit even better.

I'll be happy to answer any related comments and see if my face shield can be improved even more.

Let's make our world healthier!

PS. I added the STL file with a hole.

UPDATES!

I added 2 models for the landscape version of the A4 screen. One model is with hooks, the second with small holes in the bow.
