This version is based on the great face shield mask design by HanochH found here:
My modifications/add-ons are:
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.
02. Perforated frame
To avoid fogging up of the shield during use and for less print material consumption.
03. 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.
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:4261609
