N-gauge model railway coupling (NEM 356) with T-head

thingiverse

I use a lot of N-gauge couplings for my TTm projects and had sometimes problems with commercial ones, replacements and available prints. Finally I tried to build the coupling according to NEM 356 with some changes for better printability on a PLA printer (I use Ender 3v2, thin layer). **Files, and the numbers in the names** The first values is the length between T-bar and coupling (higher value means fare more away from the wagon box) in 1/10 mm. Second value is the height of the connection bar (in 1/10 mm) - a higher value is against distortion has other issues, maybe. I will add more variants here, if I need to create them - feel free to change and use them according to your needs. Remember - you can mirror the stl - especially the 20 (2mm) high variant can go up or down on mirroring. The 28x variant is very short, actually i have on in on of my coal cars for testing purposes. At the moment there is no lever for automatic coupling planed.
