Show your disdain for Covid-19 and any other airborne stuff that can make you sick by wearing this easy to make and very inexpensive 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.

This print uses about 20 meters of filament and takes about 4 hours to print.

Recommended print settings:

0.3mm Layer Height
5 layers top and bottom
10 perimeters (basically makes the entire print a perimeter and helps by adding a bit of flex to the material while maintaining strength).

This 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 did try a flexible TPU filament but it failed as the verticals wriggled too much due to the movement of the Y carriage and it failed.

I designed this shield to be easy to make without any "specialized" parts. That being said I strongly support the face shield designs developed by Prusa, DTM and 3cVerkstan. If you have access to the shield material and elastic I recommend it.

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.
