Cat Toy Ball

Remix from Magellannight's cat toy. Liked the look of this one and that it was a half piece for easy printing. Wanted it hollowed out though to put something inside (extra small ziplock bag of catnip with holes poked in it, a marble, a metal nut, little cat toy bell, a coin, ect...whatever you like).
Also wanted it a little smaller so scaled it down to 40mm in diameter.
Print halves, add something in the middle glue with cyano model glue and let the cats go crazy!
