                  – This kit can help you improve your print quality by getting rid of filament slippage.
                  – Aluminum doesn’t soften at printing temp like the plastic printed parts can, leading to less idler spring tension, filament slipping, bad prints.
                  – Hardware is included in the kit, but you might also need additional screws to mount heatsink with fan, for an example.
                  – Short distance
                  – Stepper Motor: 42HD4027-01
                  – See supplied datasheet for optional 57 oz-in NEMA 17 stepper motor.
