T3D-041-004 NEM HST / Mk3 Coach Couplings (Slidedoor)

Trackside3D magnet coupling kit for the Hornby HST Power Cars and newer Mk3SD (slide door) coaches with NEM pockets. These are designed to work with any Hornby HST power car with the bogie mounted NEM pocket. This design works for the newer Mk3SD coaches (slide door) with the chassis mounted NEM pockets. If your NEM pocket is mounted to the bogie of the coach, you most likely have the older Mk3 (Slam door coaches). For slamdoor NEM Mk3 coaches, you will want the T3D-041-000 pack which has a similar coupling design specifically designed for the Mk3 slam door coaches.  Note: We are currently working on a Mk3SD version of our T3D-041-000 design, so if your preference is for that design, check back soon as we have many new designs in development and test.   These models should be 3D printed upright with the open end of the cylinder facing sideways with supports enabled. You can use the Trackside3D small object profile with supports, but reduce the print speed to 10mm/sec except for trave
