Fixture Block

I started by sketching the side profile and extruding it by 100. I then extruded the cylinder by 5 mm on each side. I then made the cut in the middle by drawing the area that needed to be cut, and using the extrude cut tool. I then drew the holes on the bottom and used the extrude cut tool. After that I used the filet tool to put a 2mm filet on the cuts.
