PS: If you don't want to use my g-codes, I advice this:

•        Layer hight: 0,2mm
•        Nozzle: 0,4mm
•        Material: PLA/Petg
•        For connection pin: Infill modificator cube → infill 30%
•        10mm brim → if you will trying to print it lying, it won't fit in there (my experience ;) )
•        You can increase printing speed to 150% for shorter printing time, but when your              printer will printing connection pin, you must decrease speed down to 50%, because        the model is tall and it will sway and connection pin will be awful
