    I have noticed that the tutorial doesn't use correct measurements as shown in the diagram at the end. If I'm reading the dimensions correctly, the initial extrude should be 7.5mm, not 5.5. The diagram shows that the total thickness of the part is 15mm, not 11. Also, the distance between the 2 bolt holes at the bottom of the rod should not be 26mm from centerline. It looks as though they should be set 48mm apart, mirrored around the vertical centerline, for a measurement of 24mm from center. Am I looking at this wrong?
