Hi Chuck, I'd split it as shown in the attached snapshot. Then you would print the left side rotated 90 deg ccw so that the back of case is on the table, and the right side rotated 90 deg cw so that the front of the case is on the table. Of course you will have to design an appropriate joint for the two halves. Best Regards, Jim Scottby n6sxb - Slic3r
