This has been tested for fit on 0.030" thick visor for the Prusa Protective Face Shield. It has not however been tested for extended periods of time.
The purpose of this design is to reduce print time of bottom piece and cut time of visor by removing the three holes on each.
The print time for this piece went from 22 min to 16 min estimate on my machine.
The piece has alternating positive features on the inside track to hold onto the visor with friction. I included the F3D file to allow modification for different plastic thicknesses.
If you use this design, please verify it will survive a full use of the face shield without slipping off. I'm optimistic it will perform well.
