Tried this one a bunch of times.
Cleaned up some of the smaller detail that breaks down on printing.
Plated it in 2 files. Lower, single piece. Upper, 3 pieces.
Glue it together.
The railings on the first platform do not print with my settings and machine, but it just peels off. I'll have to delete or enlarge that in the future. Near the top of the second tier, the smaller things start breaking down, but overall structure looks good.
See the top parts on tinkercad:
Larger lower piece would not render in Tinkercad.
