I have several spare sockets, but unfortunately they are mostly without any rings that screw onto the socket.

I have identified two types of threading that slightly differs. One has an outer diameter of 40.2 mm and a pitch of 2.4 mm. The other has a 39.0 mm diameter and 2.1 mm pitch.

The freeCAD source is included so that users can easily adapt the design to different pitch and diameters, if need be.

Added a second drawing for an E14 Socket. The pitch is 2.0 mm

Using green filament, as shown in the photos, is kind of silly.
