N scale Wagon coupler PIKO compatible. It's tiny so you should use 0.25 nozzle settings (it's working fine even with bigger nozzle).
The "standard" one needs one compression spring 2x5mm, the second one is meant to replace knuckler coupler and should need some spring too (original has some plastic spring but its too tiny to be printed).
