USAT SD70 & 3-D Print Coupler Boxes, Parts

USA Trains SD70 fitted with 3-D printed Coupler boxes, etc. parts

I revisited my USA Trains SD70 with respect to its body mounted Kadee couplers.
Around year 2009, the two SD70s I have were fitted with Kadee #787 medium offset couplers mounted in an altered swinging box. Almost all my locos and rolling stock have since been fitted with Kadee centersets.

Finally, I upgraded the SD70s to centerset couplers, albeit using 3-D printed components that includes swinging coupler boxes, mounting pedestals, plug for rear pilot opening, and draft gear fairings for front & rear pilots. The coupler box accepts the newer Kadee 907 kit’s centerset coupler, springs, and lid.

For full detail see SD70 vignette hosted for me by Greg E on his Web site, particularly, Appendix H, The Ultimate Coupler Solution, CamPac BoxTM

The 3-D print components for the SD70 (and several other applications for that matter) are a cooperative effort between me and Colin Camarillo who has the 3-D printer to make the components.
