Face Shield (Updated)

A Rapid Manufactured face shield for supplementary COVID-19 PPE.

This face shield headband is designed for fabrication on a laser cutter.

This design includes slots for an adjustable strap, eliminating the need for an elastic. The strap shown in the images is 0.015” vinyl sheet that was purchased as “drawer liner”.

To reuse and sterilized, the clear film can be snapped on and off multiple times. The components are all solid plastic and able to be washed in temperatures up to 85C. (We will be shipping 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. 6 holes are punched across the top using a standard 3-hole punch – based on the 3DVerkstan Design. I chose this sheet size 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 the raw files to accommodate standard A4 acetate sheets, etc.  If you have a supply of an alternate material, and are unable to alter the 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 is best to add a bead of acetone to solvent wield 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 hope for this design:

Please use this design and share in freely among anyone wanting to Rapid Manufacture face shields. All of the 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.
