Batch-printable Face Shield

thingiverse

This design is influenced by the many Face Shield designs floating around. Specifically, I'd like to recognize the excellent designs from [3DVerkstan](https://www.youmagine.com/designs/protective-visor-by-3dverkstan) [Stratasys](https://go.stratasys.com/lp-face-shield.html?utm_source=pr&utm_medium=email&utm_campaign=mfg-amer-march-2020&utm_content=covid19) [Prusa Research](https://www.prusaprinters.org/prints/25857-prusa-protective-face-shield-rc2) I was dissatisfied with these designs due to their BOM (most require elastic bands), the fitment of the clear shield (most are not secure), but mainly with the *lack of batch-printability*. All of the designs I've seen are not stackable, which means someone needs to babysit the machine and remove parts every few hours. This design is first and foremost batchable: If your printer has a support nozzle, add a single layer between parts, and stack them as high as you like. If not, just skip a layer (requires separation with a knife), or skip several and use breakaway Supports. This design requires a transparent sheet of plastic (roughly 8.5x11), punched with a US standard 3-Hole Punch (4.25in on center). Ideally, use at least 10mil thick plastic - 100 packs of clear Binding Covers (/presentation covers) can be had cheap, just make sure they're optically clear (such as PVC; PP is hard to see through). Transparency film can work in a pinch. **Added Retention Clip to better secure the Clear Shield during rough handling. **Added Clear Shield DXF for those with access to CNC cutting equipment. **Added FaceShield_r1.1 - revised to eliminate the need for the retention clip (but still compatible, if desired). **Added Forehead - optional, adds some surface area to the forehead area for comfort if elastic is used in the back. Apply foam for extra comfort. This design fits over glasses, and doesn't require a rubberband to stay on the head. Please remember to wear proper PPE when assembling for others, to avoid contamination.
