Print 2 of this half spheres, add some steel balls (from old ball bearings for example) and glue together. I use 5 pieces 2 or 3mm steel balls and plastic glue from Revell (Contacta Professional). When printed on a heated glass printerbed, it fits perfect and seamless. Then shake, rattle and roll it.
I've printed several of them and added different counts and diameters of balls. They all sound different.
Outer diameter: 30mm
wall thickness: 3mm
