Zen Balls

Each ball will require printing the male and female halves which then screw tightly together.

The adaptors screw into their respective hemisphere to attach it to a drill for easy sanding. I suggest wet sanding for sure, but it's pretty quick and easy to eliminate layer lines and give even PLA a nice sheen, which can be further accentuated by paint or clearcoat. Fill them with stones or BBs or anything you want to give them a more beefy feel.

Included is a convenient cradle for storage.

Everything here is suitable for both fdm or resin printing but it's worth noting that the resin printed pieces don't need to be sanded.
