"King Koodoo" is an original creation by my son using Tinkercad. I suggested he try to create something with no overhangs so it can print without support material. Our prints have all be successful. The yellow print is at 100% and the gold print is 200%. We used no infill for the 100% print, but went with 10% infill when printing at 200%.
Note that the crown does not maintain contact which will require some bridging from your printer. Our Prusa had no issue other than minor stringing.
