This is a remake of the classic caps for user port board-edge connectors of the Commodore home computers. Each cap consist of a top and a bottom part with additional mounting holes. There are four variants with different openings for the cable: to the side, to the rear, both, and none.
The black cap shown in the photos is the original, not the 3D printed one.
Update: Added strain relief.
