Cat Toy - Ball in Ball

thingiverse

I've printed several variations of this cat toy style in the past using an outdated model from 2012, but encountered difficulties every time due to one problem or another. I decided to create a customizable version where users can modify dimensions and make it available for download. At the default 40mm size, one printed example turned out quite well, and I'm eager to see what other users do with different sizes - taking it all the way from tiny to huge could potentially put even the most advanced printers through a rigorous test due to steep overhang angles. When making your own print, you may want to generate support material for the bottom section in order to improve adhesion to the plate and then carefully break away the inner sphere once finished printing.
