CUBE.BALL Art Puzzle

This is a new take on my last design adding spherical sides.  The sphere is truncated to add a flat side to print on without using support.  There are three versions.  The “wide" version (my preferred version) has more of the spherical sides showing.  The ”narrow" version has less of  the spherical sides showing, but eliminates the small corner “anomaly”.  It has a slightly greater bottom printing surface.  The third version “half-round” is fully round except for the 3 flat sides.

You should print in the position the .stl files are already oriented.  I used .15mm layers, 2 side layers, 3 top and bottom layers, 15% infill.  No rafts, no support.  I used Prusament PLA.

Generally I always use the Prusa Slicr, but in this case I used S3D.   (I have not been using S3D for a long time, but found it occasionally works faster for some things; not necessarily better.)

You can triple up on your plate three times using three colors and you will end up with parts for three multi-color assemblies.   UPDATE: I have found that I get better results, less bridging--smoother surfaces, just printing one piece at a time.  Maybe it's just me.  Try both ways and see if you get better results with one or the other.

The 65mm in the title refers to the approximate diameter of the sphere.  The flat sides are about 55mm.  This is based on my recent 40mm 3 part puzzle.
