Here's a second version with a hood I added for better coverage of the forehead. As base for all modifications and add-ons I used the great face shield mask design by HanochH which can be found here:

All you need to use this is some sort of an elastic or just rubber band and A4 transparency film (inserted in landscape orientation).
My modifications/add-ons are:
01. Hood
This hood covers the forehead of the user while not being too snug. This helps with comfort and also allows breathing air to escape at the top without fogging up the shield.
02. Hooks
These added hooks allow you to attach&lock elastic bands. Also, since elastic bands are getting hard to acquire in timely manner this design makes it possible to also use simple rubber bands without having to hook them in each time you put on the mask (see photos). I designed the hooks to print at a slope without needing supports. Because this part is so small it will print fine as long as you have proper part cooling (see photo). So just try printing without supports first and only add those if needed.
03. Perforated frame
To avoid fogging up of the shield during use and for less print material consumption.
04. Wider Base at the Ends
This wider base will ensure better bed adhesion So if the original design was warping at the ends for you, now you can print without the need of a raft/skirt.
Print settings:
You can greatly increase the print speed by playing arround with the print width and allowing "single extrusion walls" (term used in simplify3d). This way when it comes to thin walls such as the hood instead of a zigzag infill the printer will just extrude a signle line. With these settings I print each face shield in about 2 hrs: 0.48mm print width, 0.2mm height resolution, 2 outer perimeters, 30% infill.
Files:
Here you will only find the .stl file. Since uploading .step files is not possible here you can find it in my post on Thingiverse: https://www.thingiverse.com/thing:4275483
