Model information

This replaces the housing core part of the Annex Engineering's Sherpa Mini Release 2 extruder to accept an ECAS coupling for the reverse Bowden feed. 

Has non-round geometry to allow printability and minimal force to push-in. Other designs may crack if excessive force is used to insert the ECAS coupling.

Allows compatibility with multi-material feed systems etc., and more reliable reverse Bowden connection.
