What are the diamentions of 28H2P3205A4 sold on Arduino webpage

Sorry if this is wrong forum but I found several conflicting sizes of 28H2P3205A4. Where can I find technical drawing of this motor including spacing of holes and shaft?

As it's sold in the Arduino store, I think it will be best to contact them and ask for the datasheet: https://www.arduino.cc/en/contact-us/.
