Fast Face Shield (Updated)

thingiverse

A Rapidly Fabricated Face Shield for Supplemental COVID-19 PPE. This face shield headband is specifically designed for fabrication on a laser cutter. The design includes slots for an adjustable strap, eliminating the need for elastic. The strap shown in images is 0.015” vinyl sheet that was purchased as drawer liner. To reuse and sterilize, the clear film can be snapped on and off multiple times. All components are solid plastic and can be washed in temperatures up to 85C. We will ship these face shields with multiple sheets of clear film per headband. The face shield film is based on a 10.5” x 12” sheet of 0.010” Polycarbonate. Six holes are punched across the top using a standard 3-hole punch – based on the 3DVerkstan Design. This sheet size was chosen based on a large supply of locally available materials. The larger sheet size also provides better coverage over the neck and cheeks. However, the pin spacing can be changed in raw files to accommodate standard A4 acetate sheets, etc. If you have a supply of an alternate material and are unable to alter raw files, please just ask – I can happily help out. The headband is cut from ¼” and 1/16” ABS. The design snaps together, but it's best to add a bead of acetone to solvent weld it in place. A piece of ¼” EVA foam is added across the forehead for comfort. This piece is not necessary, and can be removed for cleaning if desired. My goal with this design: Please use this design and share freely among anyone wanting to Rapid Manufacture face shields. All cut path files along with an overview PDF are available. I've also shared the original SolidWorks CAD files that can be modified as people see fit. May everyone stay healthy and happy.
