Wagon Couplings Test - Test Stands + Decoupling Tools (various systems)
Description:
I share this set of test stands (the yellow pieces) for testing how couplings from different brands fit on your wagons before final installation.
Includes:
Red stands → for mounting and testing couplings from various brands to check compatibility, height, and actual operation.
- Yellow clamp (clamp-type decoupler) → practical tool for comfortably disconnecting the couplings from the stand without damaging the parts.
- Yellow square (square/decoupler) → ideal for easily decoupling wagons.
Black couplings → two different versions optimized for printing with a 0.2 mm nozzle.
Important: Do not modify the print profile of the .3mf file → it is specifically configured for Bambu Lab matte black filament and provides excellent results in detail and finish.
On the underside of each ring-type coupling, there is a small slot designed to insert a piece of 1.75 mm filament → this greatly facilitates manually opening the couplings between wagons when needed. (see image with small piece of red filament on black coupling)

I hope this helps you test combinations, adjust heights, and see which couplings work best for your projects. Print, test, and tell me in the comments how they look on your wagons! 😄
Any questions or suggestions for improvement, I'm listening!
Happy printing and happy railroading! 🚉⚙️
