Sure, it you have the industrial tools needed for that. The Prusa shield needs a 3D printer (which many have or know someone that have it) a piece of laminating foil & hole punch (which you likely have if you have laminating foil). This way it can be made locally from local resources.

If you have a factory that can make a face shields by the milion, definitely go for it! Still, you need then to transfer the finished shields to all the many places that need them, which can somtimes be tricky with all the lockdowns and border checks in place.
