I started by sketching the side profile, using the front plane, then inserting a circle extruded cut through the entire model with a radius of 53.25, starting at the midpoint. Then I added another circle extruded cut only going 75mm into the model with the radius of 85, starting at the midpoint and using the front plane. Using the right plane, I inserted a straight slot cut extrude at the bottom of the model, and a rectangular cut extrude at the top of the model. Lastly, using the front plane, I inserted a rectangular extruded boss base at the top left side of the model, making sure that it lines up with the backside of the model.
