How about making something that takes standard Sinar type boards? 140mmx140mm?
That's about 5.5 inches right? That would work. I'm going to have to buy a metric ruler! Not only that but my Grizzly table saw ruler is in inches. I'll have to do actual math to convert to the exact size. That might overload my little brain.

Sinar is a pretty popular maker. Anyone know what Deardorf and Wisner do for lens board sizes?
