Summary

Tram Couplers for HO scale, including mounting bolts and plates (Shifties).
Use them for your projects. Please note that the holes in the Shifties will need to be reamed out.
Edit
I added Shifties that have a holder to limit coupler Swing and manage height of Couplers. And a Loop Coupler (not tested)
Please note that the couplers are designed to be used with light models and short consists. For optimum strenght print them in PLA+ .
