Foam frames for faceshields

This presentation summarizes simple design sketches, instructions and comments on faceshield with a foam frame.

I rank these among the best perfoming faceshields, but most of all they are easy and fast to make in numerous countries where expanded polymer (foam) techology is available.

I acknowledge it's not very creative, it's just design "by the book", so I don't claim any ownership or expect any type of compensation for its use.

I do offer technical support using nonlinear FEA for a fee in case you need help customizing or fine-tuning your products.
