The absolutely gigantic model that could test how long your printer could go without breaking, exploding, imploding, freezing, thermal runawaying, or running out of filament. MAKE SURE you have a brand new roll of filament before beginning. Use the highest infill possible if you want to really make a waste of plastic that you could use as a wheel brake for a car. This would be an absolutely insane print and I dare anyone to actually do this.
