Designed to fit NEMA 17 Stepper Motors, and can accept the Raptor Universal Filament Drive Gear and other similar size drive gears. For 1.75mm filament only. Compatible with Prusa mendel, Prusa i3, rostock, and all reprap printers.
The Airtripper’s Direct Drive Bowden Extruder design is now stronger than ever with a much cleaner 3d printed finish, and filament changing is now easier than ever before.
