Shell for cheap jaycar mini XLR connectors. like the one linked below.

Designed for the 4 pin version but i believe the 3pin version is the same size, can't confirm this though.

Has a wide 6mm hole at the back to suit cables with paracord sheathing or larger gauge cable. current version doesnt have a retention so i recommend adding some glue heatshrink on the cable to create some retention against the rear of the shell.

Prints pretty well just throwing it face down without supports. Also printed with a pretty standard .2mm profile and tolerances were good.

Credit to Areleaux with their original design that i reworked to fit this connector. Link to their work below.
