I don't have a drawing now but the design is very simple. 18"x12" acrylic sheet with 6x drilled holes and a 8.5x11x0.060" depression milled in the center. I'm located in LA and commute to OC often so something in that area would be best. Feel free to suggest a material easier to machine than acrylic - must be a plastic and preferably clear.
Thanks in advance.
