N scale train trestle

thingiverse

Set of progressive 2% grade trestle. The shortest one assumes a start one mile from the beginning of the grade (assumed to be dirt/gravel ramp) and ends at a height suitable to overpass another track with a scale height of approximately 20' they are scale 12" square beams. I made the track runner beams from balsa strips to tie it all together. With the was Prusa sliced them and it's print direction...they look like wood lumber.
