This is a rattle, is intended as a toy PLEASE be careful, there are small parts inside and resin 3d print can be toxic if lick or put in mouth
There 2 handles, one is in 2 partes and the other is complete, print the one that is easy for you
There are also the small balls that's goes inside the big ball, you can skip this if you have something else to replace with
If you are printing with a resin 3d printer, after washing but before curing, Threads the parts a couple of times, this will lose them, after that cure as normal
