The file 'Gears For ABENICS Active Gear Joint 3D Printer Model' is (stl) file type, size is 6.5MB.
Not yet printed gears modeled after the crossspherical gear and monospherical gear used in the ABENICS active ball joint created by Kazuki Abe, Kenjiro Tadakuma and Riichiro Tadakuma.

The monospherical gear is still rough at the base of the teeth, but I couldn't come up with a way to clean it up properly. For the Crossspherical Gear it would probably be best to split it in two halfs for printing.
Please share your results if you print this, I am curious to see if it works!
EDIT 22.06.21: Fixed mistake in the gear pitch resulting in 'skinny' teeth in the spherical gear and too wide teeth in the monopole gear.
EDIT 28.06.21: Pitch still wasn't right, should be fixed now
