Voronoi Cat Toys

Looking for a new cat toy? These four Vornoi variations travel irregular paths when tossed or batted with a furry paw. Better yet, you can include a small ball to make them rattle.

These are named for their number of cells: 50, 100, 150 and 200. The lower the number, the weirder the path. The highest number, 200, rolls almost normally. All are strong enough to survive attacks of normal housecats. No guarantees for their larger jungle relatives.

Each cat toy is a bit more than 40mm diameter. The included ball is 24mm diameter. You do not need to include the ball, but it's easy to do:

• Print the ball
• When you slice the cat toy, insert a pause at about 30mm height (75%), then slice again
• When the printer pauses, insert the ball
• Resume the print

You do not need supports or special settings to print the cat toys. In your slicer use a Place on Face or Auto Orient command to position the base of the model on a flat cell, then set a 15mm brim to anchor it to the print bed. I print them in ABS, but PLA and PETG will work as well.
