I could not seem to find any publicly available library with the XT60 connector for KiCad or Eagle so i created one myself.
This one is Through-hole mounted, it’s not made for pcb mounting but it dosent really matter.
The part i created it from has the following dimensions:
Diameter of the pins: 4,5 mm
Pin pitch: 7,5 mm
Size of pads: 6 mm
