This toy is a re-creation of the Master Emerald from the Sonic franchise movies and games, modeled after the one seen in the movie. My kiddos wanted one to play out their imaginary boss battles at home. The edges and corners are rounded slightly to prevent injury. The 3MF file uses two different sections of sparse infill to provide strength close to the walls while reducing filament usage in the middle. Default print is 200mm corner to corner, which was large enough for the kiddos to feel special toting it around, and used about 250g of material. Prints upside down without supports on the A1 in ~10 hours. You may need to blunt the bottom point on it, as it printed slightly sharper than intended, but otherwise requires no post-processing.
