Here is my design for a chassis mount Anderson power pole socket. I've included a large number of versions of files for different configurations on conductors and sockets.
The connectors will slide in from the front, but are prevented from pushing all the way through by protruding keys.
The models also have holes which align with the hole in the connectors where you would typically add role pins. A length of standard 1.75 filament can be inserted through these holes and through the connectors to lock them in place.
I also included a number of "voids" as STEP files. These models can be used to add the same kind of connector to existing project by subtrating one of these STEP files existing geometry.
The author marked this model as their own original creation. Imported from Thingiverse.
