Hi Mattew,
No problems. I can do them as well if there is any interest n these masks.
However there may be some issues with 3mm thickness of material I'm using. According to
http://www.btinternet.com/~gfcarey/careymask.htm 3mm isn't good and it's recommended to use 1.9mm
Also there is a question about copyright. is this design legal to produce? I am not so good at this stuff. At least with Bahtinov's mask I had an idea and I could contact Pavel to arrange all these things.
Anyway I can try 3mm thickness with Carey's mask design and compare it with the same made from something thinner. If 3mm thickness works and somebody wants it I can just cut it. In this case I won't offer a mask itself to avoid any legal issues. I will offer cutting service for any cut pattern that customers want.
Also if anyone has ideas on new mask design but it's required to be tested I can do it. We can find some cheap material like A3 heavyweight paper to keep the cost down and I will cut as many combination of new design as needed for lower fees.
I can cut foam, MDF, pine(tried up to 15mm and it works) and acrylic if it can be cut from panels no bigger than 24"x12". I can even create some complex shapes from thicker foam, wood or acrylic if stacking thinner parts together isn't a problem.
