I lost the pigtails that came with a MTH traffic light and controller and was able ID them as Molex products and found the 3D models on the Molex site. I didn't have the original contacts but was able to make minor modifications to the 3d model and get the contacts from some cheap pigtails I'd found online for a different project to work by reducing the space inside the connector. See Molex Connector Part Number - 50-37-5043 and Molex Connector Part Number - 50-37-5023 for access to the 3D models.
Can't post my modified models due to license concerns but wanted people to know that there is an alternative to having to purchase bulk quantities.
Printed them on a Prusa Mini FDM printer with .25 nozzle at .1 layer height.
