Meet Renegade: a 3D printing pen that lets you use plastic bags and bottles to bring your ideas to life. It can use 5 to 7 mm strips cut from PET plastic bottles and plastic bags. You can also use PLA, ABS, nylon, wood, and other types of filament. You also get the ChupaCut, which is a plastic bottle shredder to provide plastic strips for this 3D pen.
Renegade has an aluminum structure and lets you draw in the air to bring your designs to life. It is expected to ship in January 2017.
