New-to-me Rockwell vertical milling machine came without a knee crank. Quick design and 3D print of a crank arm and a modified bicycle pedal to the rescue.

How I Designed This
Quick design in F360. The critical dimensions are the cylinder/hole to fit the knee axis and another cylinder/hole for the pedal connection. Also arm length is 6" to keep enough clearance with the rest of the mill.
My initial plan was add bolt holes to mate up with the holes on the mill, but the print is tight and the arm is light so I'll just use the friction fit for now.
