snap on clip for glasses and hats for face shield

thingiverse

These face shields snap easily onto glasses or hats, giving you protection from potential hazards. They work well on safety glass and also fit regular glasses, depending on the frame's thickness. People who wear hats like them because they clip onto the brim with ease. Designed for frames that are 3.2 to 4mm thick when made of PETG material, but may be able to handle thicker frames if using a more flexible material. The face shield has a lip at the bottom that pushes it away from your nose slightly, keeping it from touching your skin. We use them with clear lenses, which are not perfectly clear but still sufficient for our needs. https://www.amazon.com/gp/product/B0015ZVXIW
