Face Shield Visor for Small Bed #3DPrinting #PPE #CoVid19

Over the weekend I designed a face shield visor that can fit on a printer with a build volume of 150mm x 150mm. Most popular face shield designs such as the 3DVerkstan or the Prusa RC3 require a build volume of at least 160mm x 185mm and 191mm x 144mm.

Taking design considerations from several open source designs, the visor is thin and flexible so it fits across the wearers forehead. It supports an 8.5in by 11in 3-hole punch sheet, which can be either PETG or transparency film. Because the frame of the visor is only 1.5mm thin, the majority of the geometry is solid perimeters and doesn’t require much infill. This allow the visor to print in just under an hour, 50 minutes, but could be even quicker with optimized slice settings.

Sophy Wong’s Add-on is used to cover up the gap in the top of the visor. This excellent design attaches to the existing pegs on the visor and features foldable tabs that nicely cover up the gap. I was able to cut the design out using a vinyl cutter.

With proper coverage, the visor has enough clearance for hefty sized safety goggles and a surgical mask.
