Shorter Headband for Face Shield with Closed Top

Modified an existing remix to close the top on the RC2 style face shield.

The remix this was based on is slightly shorter than the Prusa version to reduce printing time and filament usage. The model with no hex holes was selected to limit exposed skin. In addition the top open portion as been closed. This will slow printing time, but should provide greater protection from droplets going over the top of the face shield.
