Clip on Face Shield

prusaprinters

Pre-Face. If you have the materials to make the Prusa Shield https://www.prusaprinters.org/prints/25857-prusa-protective-face-shield-rc2 please do that. This project was designed to use common parts, 1 printed piece and one 2L pop bottle, and require no special tools (other than a 3d printer and a knife). Most importantly I haven't been meeting with any Health Ministers and Prusa has! I have added a longer version of the shield that will require a larger piece of plastic than a pop-bottle, think overhead transparency sheets or similar. The longer version is 270mm x 210mm and was the tallest I could get due to the restriction of Z height. Show your disdain for Covid-19 and any other airborne stuff that can make you sick by wearing this easy to make and practically free face shield that clips on a baseball style cap. The shield part is cut from a 2 liter soda bottle (the one I used was root-beer!). Cut the plastic to 270mm x 150mm and slide in the top of the frame. The part that clips to the hat has some 1mm supports built into the model. After printing I just cleaned them out a bit with a needle file leaving the inner surface of the clip a bit rough so it will grip the brim of the hat better. Disclaimer: It sucks to have to add this but I am not a medical professional and use of this shield has never been shown to provide any protection against germs, bacteria, or viruses and is why I have listed this under "fashion accessories". If you choose to wear this outside where you may come into contact with others please follow the guidelines of the WHO and CDC during the Covid-19 crisis. Print instructionsThis particular shield was printed with transparent PETG. What ever filament you use it needs to be somewhat flexible so it can fit caps of different sizes. I tried printing with TPU but was having issues as the vertical portion wiggled too much during the print and it failed. Included is the 3mf file with my slicing preferences. YMMV
