NEMA 17 - Model: KH42JM2B247

I found this data for them:

Quote

current of 1.2A

0.38 Nm torque
axle gear belt with a diameter of 13,4mm and 10mm wide working area
6 wires output

You will need to either remove the pulley, or find a compatible belt. But apart from that, those motors are suitable for a 3D printer.
