This work is inspired by Prusa Research's face shield design.https://blog.prusaprinters.org/from-design-to-mass-3d-printing-of-medical-shields-in-three-days/

We modified Prusa face shield design and make it more suitable for hospital used.

1.  We add face shield locking feature to prevent shield slip out. 

2. We reduce the face shield height to 5mm. Now you can complete your print in 40mins ( 3rd of Prusa RC2 2h) and use only 13g filament ( less than half of the original Prusa RC2)

3. We stack up 10 face shields together and make it suitable 3D printing in large quantities.
