I created this model to help me design a housing box for a DMX/XLR gadget. The model can be imported into CAD to have a place-holder for XLR sockets or it can be printed to have something physical to match to a socket or housing.

There are two example plates: a complex one that allows the socket to be installed in one direction only and a simplified one that allows installation in two directions.

Note: if (like me) you only create two screw holes in a plate - make sure the orientation is correct, otherwise you will not be able to install the socket (use the socket stand-in to check).

The socket model can be used virtually in your CAD system as a stand-in for the real socket, or printed for volume checks on real hardware if your real sockets are on back order.

The stand-in has a more or less typical front plate, a volume to mark the front extrusion of the socket, a typical barrel, and an exclusion volume for the solder cups at the back. Please note that this exclusion volume may not be big enough for adding your wires, so leave some space behind it.

Files

I included GCode for the Prusa MK4 for convenience. If you want to re-slice, use the included 3mf project - it includes a marking of the “outside” wall for the example plates.

The STL files can be used for printing or for CAD import.

The entire FreeCAD (v.0.21) model is included for perusal and adjustment.

A technical drawing (PDF) is included to give some explanations and dimensions for your own designs.

Update Jan. 2025: I changed the license from GPL3 to Public Domain to allow more use cases.
