THIS VERSION SUPERSEDES PREVIOUS "ARC" VERSIONS (which will not be maintained)
The parts are at HO scale. Reduce at 55% for N scale.
Prints without supports. Just use brims on some small extremities touching the bed.
Print the column flat (rotate 90 degrees on Y axis).

I used the ORCA slicer and test printed on Bambulab A1's.
The model is functional, but can still be modified/enhanced.
