arista face shield

Minimalist face shield design created with a focus on speed and simplicity. The goal was to produce a basic shield that could be printed quickly, drawing inspiration from the PRUSA open source design. To streamline the process, the bottom bracket found on the PRUSA design was eliminated, as it added unnecessary time to the print and provided little value. The frame was thinned down to 0.25" thickness for better efficiency. An elliptical contour was also incorporated to fit comfortably around the head, offering a more comfortable experience than the PRUSA design. The print settings used were: 52 minutes, 17.48 grams of PLA material, no rafting, 100% fill, and supports enabled on a Makerbot Replicator 2. It's possible that faster prints can be achieved with lower fill percentages. To create a shield, laminated pouches from Staples (5 mil, 9x11.5") are needed. These should be run through a laminator empty to clarify and stiffen them. Mark the holes and curves on the laminated pouch using a jig. Align the top left corner mark holes, then the bottom left corner, tracing the curve. Flip the jig and repeat on the other side, using a single hole punch for accuracy. Place the laminated sheet on one side of the frame, applying tension to stretch it onto the holes. This process should be somewhat challenging to ensure the shield remains secure during use. This design has not been validated and is not intended for use as eye or face protection. Build and use at your own risk.
