This is a funny little (3) legged bowl or pot. I hope to cast this in porcelain someday. I sanded, primed, and painted the one in the photo in preparation for making a plaster mold. It's sloped toward the front to give it a more dynamic feel. Future versions might be more spherical, have holes, more facets (I need to model this in Fusion 360!), have chimneys. All versions will be a little odd! :-)
Update 9-18-19: Redesigned on fusion 360 for smoother surfaces.
Print with support for the bottom of the sphere. The support won't be very tall, so you probably don't need a brim or raft.
Scale this up on your printer to suit your needs. Scaled by 1.6X yields a sphere about 80mm across or about 3 inches.
Recently redesigned on Fusion 360. More to follow!
