ZipVisor FaceShield

youmagine

This design enables high-throughput small-scale production of protective face shields for healthcare workers and others exposed to hazardous materials. It fits comfortably and securely on any head size, making it a versatile solution. A US/EU style hole punch can be used to add holes to the transparent sheet. UPDATE v20: I've modified and simplified the brackets for easier assembly and vertical stacking. The brackets can easily be separated with a flat-head screwdriver. X2, X4, X8 vertical stacked models have been added, intended for 0.3mm layer thickness and 0.6mm extrusion width (0.4mm nozzle). I've chosen to use zip ties as the primary component and designed simple brackets to hold the transparent sheet. This reduces print time to approximately 15 minutes per set and enables a stacked plate of parts, allowing one printer to produce 20-50 full visors per day with sufficient zip ties and transparent sheets. Suggest printing in PLA or PETG. Zip ties measure 4.8mm x 360mm. The design should fit any head size and provides a fairly comfortable and secure fit. Possibilities for sterilization remain uninvestigated. NOTE: This design is a work-in-progress with very limited real-world testing. I designed this to accommodate a Swedish hole punch with a 2-hole footprint, but it appears that the rest of the world uses single-hole punches. I've added a universal bracket that should fit any 6mm diameter hole, allowing punched sheets from various sources.
