<p>Our face shield's greatest advantage is that a new visor can easily be created with a 3 hole-punch and transparencies (such as laminate or project film). The OPP hole-punch face shield frame took inspiration from other models available online such as the Prusa RC3 and 3DVerkstan face shields. While these models are certainly great, we built on them to create a more convenient model without sacrificing strength and comfort. We applied the principles of value engineering to design an effective face shield frame that features a remarkably convenient 3-hole punched visor and an elastic band for adjustability.&nbsp;Our face-shield just requires a three hole-punch and an elastic band to assemble. Any laminating film, projector film, or comic protector works well. The visors come delivered and punched; however, if at any point the visor needs to be replaced, this can be done easily with little hassle or expense.&nbsp;The frame itself is lightweight and comfortable with the help of the elastic band. The design will not squeeze your head from the sides to stay on; the user can adjust to whatever is most comfortable.&nbsp;This design does not have thin crevices or a multitude of surfaces that are difficult to clean, where dirt or bacteria could accumulate. This provides for good reuse-ability. When the visor gets dirty, it can either be cleaned or simply replaced. The shields are designed to last. The elastic was kept as essential for comfort and adjustability. The consequences of the mask falling off in an exposed situation are simply too great to accept having a mask that isn't adjustable to fit every user.</p>
