Easy to print and fun to play with. The sound produced it's really nice. Only flaws to report is too much support at the bottom of the sphere, which left many marks(maybe the tree one would works better; may retry to print it in the future) and some marks at the top(no idea if it's because of the design, the filament or what else). Mine is bicolor cause I assessed a wrong amount of grey left and so was forced to use some other color to finish it, but it still looks good ;)
