Manual decoupler for model trains (H0)
thingiverse
Though manual decouplers for model trains are no rocket science, I found none that fit my needs. So I designed one by myself that is tough, easy to print, pleasant to handle (even in the cramped confines), needs no support and can deal with many hobby and toy grade couplings. This one was tested with old Lima™ couplings and Märklin™ Relex™. You might run into trouble with short couplings but feel free to test on your own. I added a groove in the middle so it's easier to center the tool between two cars (visual highlighting recommended).
