This is a manifold remix of the Fancy Tower by PatrickIsMe. The original was really nice - well done Patrick - but the overlapping objects caused confusion in some slicers. Used Blender selection by linked, boolean modifier, and 3D print toolbox to fix.
Original file was a bit too small and the tab holes not shaped quite right. This version should provide a better fit.
Also rotated the file for optimal print orientation.
One issues with this version is that the tray that holds it has a small bump that usually pokes into the slot on the side of the cardboard tower, but the holes in this version do not fit. Thus, the tower is slightly lifted on one edge when sitting in the tray. See attached picture. Not enough to cause any problems; it all fits quite nicely in the box.
