Summary

This is a remix of Braykrenz's "LegoCompatible Train Cow Catcher" (https://makerworld.com/en/models/230078).

I shrunk it down about 60%, removed the original Lego connections, and added a new Lego connector. My connector is designed to fit a 1x2 brick.

I wanted to change the look of my little saddle-tank engine. I didn't expect my first "test print" to work, so I didn't bother changing the color of the filament that was loaded in my printer. But it fits, and even though it's a little over sized, I like it! So I'm going to keep it.

I realized pretty quickly that the catcher fits IF the train is riding on its flanges. But if you were to put this on a track, the catcher would hit the rails. So I've included the FreeCAD source file in case anyone is interested in making any adjustments.
