I recently started experimenting with 3D printing for my model railway, and I’m amazed by the possibilities—from custom signal boxes to tiny detail parts that would’ve been impossible to find off-the-shelf.
I’d love to know: what have you designed or printed for your layout?
Do you have a go-to printer, filament, or CAD software? Any tips for beginners trying to get accurate prints at smaller scales (like HO or N)?
