Arch bridge for brio-style train tracks. I made this as three separate pieces so you can print only the piece you need or the whole set as you like. I had the two ramps but was missing the arch bridge, so I started with that and decided to model the whole thing. Both ramp styles can be printed to have a continuous male-female ends, or two of one style to have a male-male or female-female transition, conductor's choice.

Printing suggestions:

-Ramps can be printed as they rest normally, 2+ walls and ~10% infill is sufficient.

-Arch Bridge was designed such that it can print on its side with no supports. I would recommend 2+ walls printed with the Inner-Outer order to improve overhang quality. 

This is my first published model and was fun to design and print. I welcome any and all feedback (especially if you know how long/tall the arch is actually supposed to be).
