FaceShield for ISO 838 - 888 holes This shield was created for the Open DIY Projects FaceShield project at https://open-diy-projects.com/doityourself-gesichtschutz-faceshield/ (they are now printing another design for Prusa-visors) Based on the Prusa faceshields, thinking of shorter printing times and less material usage If you want to make 10,000 sets, we need to think about it... For the Prusa faceshields, a laser cutter is needed to cut holes in the shields, which is not possible for everyone, such as people at the supermarket, so I changed to ISO 838 - 888 (hole distance 3 x 80 mm) This can be done with an ordinary office hole punch with the "888" guidebar setting on a DIN A4 sheet of 297 mm I added a hook at the forehead for buttonhole tape to the back to prevent sliding to the nose - Print size: 180 x 140 mm - Short printing time - Less material (<30g for headband) - Hook for overhead band xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx English: This face mask was created as part of the Open DIY Projects FaceShield initiative at https://open-diy-projects.com/doityourself-gesichtschutz-faceshield/ (they are now printing another design for Prusa-visors) Based on the Prusa face shields, thinking of shorter printing times and less material usage led to new designs If you want to print 10,000 headbands, this will be an important factor For the Prusa-based visors, a laser cutter is needed to cut holes in the shields - this is not a solution for "everyone", such as people at the supermarket So I changed the attachment for standard DIN A4 sheet four-hole punching This can be done with an ordinary office hole punch with the "888" guidebar setting (hole distance 3 x 80 mm) on a clear plastic sheet of 297 mm (DIN A4) I added a hook at the forehead to attach a headband to the back, preventing it from sliding down to the nose For attachment, regular buttonhole tape is used (18-25 mm is recommended, such as Prym Knopfloch-Elastic https://www.prym.de/p/knopfloch-elastic-glattes-band-18mm-schwarz-1m-19560420) - Print size: 180 x 140 mm - Short printing time - Less material usage (<30g for the headband) - Hook for headband PETG is recommended, but PLA also works well The "Stacking" are support structures to print two on top of each other (Z-Offset + 20.5mm) Update 2.4: Reinforcement improved
