The file 'Motorized Gear Sphere 3D Printer Model' is (stl,step) file type, size is 8.3MB.
I took whosawhatsis' thing 6499 eccentric sphere gears and modified it to have a base for a motor mount and battery pack.
I also converted the scad file and all the gears into STEP files so further editing can be done.
