Hi Bob No, i didn't have any plans. I just went slow and measured twice, three, and sometimes four times. I used 1 by 12 poplar that was 6 feet long. Hardly had any waste left. The sides are 13" tall the back is 12 1/4" tall. The Top, back, bottom, and the little piece in the front are all 8 1/2" wide. Then I cut a 1/4" deep groove down the two sides and the bottom for the clip board to slide down into. The clip board is 9" wide. I used glue and a finish nailer. I could try to doctor up the picture for you if you like. Hard to explain in words.
