Voronoi Skeleton Balls

Voronoi patterns provide seamless changing cells on the surface of these four hollow balls. The numbers are cell counts for each pattern: lower cell counts produce coarser surfaces, higher are finer.

Each ball is about 65mm in diameter, just a bit smaller than a hard baseball. It fits comfortably in most adult hands (for smaller mitts you can scale it down in your slicer). You can use it however you'd like: roll it in a line to make a border, in a wavy path for wild decoration or freeze frame to make a unique stamp. Diameters vary slightly depending on the thickness of the struts around the cells. These vary from about 1.5mm to about 2.75 radius.

If you're using them as stamps, they'll clean up easily with a jet of water.

Scale them down to make fine cat toys.

The photos show a number of Voronoi Skeleton Balls I designed and printed in the course of developing techniques. They are representative: models shown in the photo may or may not be uploaded here. All my designs are carefully designed and tested. I can generate additional cell counts if people show interest.

Are they printable? Yes: with the help of supports. I've had good results with basic supports and a wide brim from the build plate (don't use tree supports). The support structure generally snaps off cleanly. I've printed these in ABS but PLA and PETG should work fine, too.

If you want to encourage this project please leave a comment and show your results. Suggestions welcome. Thanks.
