Modmaker 510 squonker connector locking mechanism (large nut)

Simple locking mechanism for the Modmaker 510 squonker connector. You need a pretty accurate printer for this. (SLA/Resin printers preferred - Or print it via a 3d printer service in SLS)

This is the version for the optional large positive nut.
