The original housing looked already great, but I needed to create an adapter from female to male with a crossover pin-layout - so I removed the rear part of the original housing, mirrored the other half and put both together to get a double-sided D-Sub housing.

The author remixed this model. Imported from Thingiverse.
The original was a simple cable housing, the remix is a housing for a double-sided adapter-plug.
