A bridge for brio tracks. All three passages will fit tall thomas&friends toysets. Fits on Prusa i3 printer size. The slope is 35deg, so self-moving locomotives might not be able to climb it. Print two times and join the halves with bone-joint.

Will fit Prusa i3 printer. Print with PLA either as standing with organic support or lay it on the side and use snug supports (uses less filament). Infill was set to 7%.
