Version PFS7 is designed for attachment with readily available rubber bands Remixed from Prusa Protective Face Shield - RC3 Thanks Prusa for the orignial design and initiative! Print instructions Prints fast and beautifully. For cleaner printing place bottom piece above head band and set your slicer to avoid crossing perimeters. Remember to sand inside of head band with 180 grit sand paper as people will be wearing these for 8 hours at a time and comfort is important. If printing with 0.4 mm nozzle: Must use 3 vertical shells (stronger and faster to print) 30% infill. (20% is too weak) 0.3 mm layer height PETG preferably Visor cutting instructions Laser cut the sheet Leave protective film on. Most people are using 0.25 mm PETG visors
