Faceshield PFV covid-19

Covid-19 face shield, PFV-I, with the following capabilities:
- long visor upper protection
- no need of a hole puncher
- no need of an elastic band
- extra ventilation on the visor to decrease breath condensation at the protective sheet

Three versions available:

- PFV-I regular size face shield
- PFV-II mini, optimized version for quick printing
- PFV-III mobile visor, adjustable protective sheet (due to compression of the file, the finishing of the clipping part is not as clean but it is easy to separate with a knife)

Note: Not yet tested at the hospital, please let me know if you get feedback at one!
