Step 12:

Place the 6.125” carbon tube assemblies on the other two sides to create a cross like shape with the carbon tubes. The holes on the points (2.125, .875) and (1.375, .875) on one of the carbon tubes of one of the 6.125” assemblies. The holes on the points (1.375, -.875) and (2.125, -.875) should lie on the other carbon tube. Make sure the motors are facing the same direction. The holes on the points (-2.125, .875) and (-1.375, .875) on one of the carbon tubes of the other 6.125” assemblies. The holes on the points (-1.375, -.875) and (-2.125, -.875) should lie on the other carbon tube. Mark the holes using a center punch.
