Step 9Cut squares
iImage Information

I measured each cubie to be 19.1 mm on a side, and each sticker as 15.6 mm, about 81% of the size. So I rounded up to the nearest 5 mm (165 mm for a "sticker" for a 200 mm cubie) and ripped much of one sheet of 1/4" plywood into 170 mm strips. I then set a stop on my miter saw to 165 mm and made two cuts for every square, to ensure the 54 squares were as close to perfect as possible. I ganged them all together with a strap, and routed and sanded the corners of all squares simultaneously. This step was pretty quick, and all the components were done now. Just painting and hardware to go!
