Mini train - under 20mm

A cute, stylized mini train designed for FDM printers (tested on Bambu Lab P1S). The model fits within 20 mm and prints in a single piece — perfect as a test print, collectible miniature, or fun little desk accessory. It captures the iconic look of a classic locomotive (engine body, chimney, wheels, and cab) while keeping all parts thick and easy to print, even at a tiny scale.
