This is an adapter, to use a pole with cone threaded connector (as e.g. the Vileda ones) with the M24 connection mops, commonly used in Greece.
It is a combination of the “Vileda Mop rod, Coned Thread Connector” designed by Skaran (Vileda Mop rod, Coned Thread Connector by Skaran | Download free STL model | Printables.com) and a M24 bold, designed by me.
The reason is to use a robust pole having cone threaded connector with the commonly available mops in Greece, which have a M24 female connector.
The used organic supports (see Mop_Connector GR.3mf file) gave a perfect solution to good quality printing.
