This cam has room for a 608 bearing (standard skateboard bearing). This allows the axle to spin freely within the cam, which results in much smoother motion and makes the cam less prone to failure.
I took advantage of the fact that akak's "axle.stl" model is already a snug fit inside of a 608 bearing.
As-is, everything should be a very snug fit. I didn't have to resize these models in the slicer, but it did take some wiggling to get everything in place.
Simply suplerglue the bearing into the cam (it is a snug fit, but can be pressed in by hand), fit the axle through the inside of the bearing, use a long M3 screw to fit a washer on the end of the axle (to prevent it from sliding out of the bearing). Then place the cam on the motor shaft, and insert a set screw (I used an M4 screw, you could also use an M3 screw with a threaded insert.
Use this at your own risk. This model includes parts under tension, which poses a risk of injury.
