This is a model of Cinderella's Castle from Disney World.  This was originally made for the FlightGear open source flight simulator a while back.  If you know where to find it and you try out FlightGear it should still be there.  Scaled to just under 9 inches tall.

There are 3 versions in the files.  One with the walk through tunnel, one with the tunnel closed up and one with a big cone on the bottom so it can used as a tree topper.

Made using AC3D.

Print Settings:

Suggest 3-5 walls and 15-30% infill.  I like to use adaptive cubic infill or 2-3 gradual steps depending on the slicer.

Recommend no smaller than 50%. Printed one at 50% and one at 75% and it printed nicely at 75%. Slow it down a little in the slicer so it catches the detail. Took about 8 hours to print at 75% size at half speed.

Also, printed at 100 percent. 0.28 layers 30% cubic infill with 3 gradual steps, and 3 walls and it took 14 hours to print.  This was a while back so with today's faster printers results should be better.
