Remixed Prusa Protective Face Shield - RC3 with Tabs for Foam Insert

I've remixed the rc3 model to include three small tabs to hold a foam insert to fill the gap at the top. It's designed to hold 3/8" thick foam but in my testing with 3/8" EVA foam the frame becomes quite rigid, surprisingly so. A thinner foam or more flexible foam would probably be better.

Another option would be to bend the frame slightly while tracing the outline onto foam, then cut the foam in the slightly bent shape. I think ideally you'd want the foam to fill the space that is created when the headband is worn at a comfortable fit.
