UP! Mini Extruder/Stepper Motor Extra Fan Mount

thingiverse

UPDATE:\nSome critical adjustments were made to this area: \nadditional mounting for an extra magnet has been incorporated at the base, \nattractively located holes facilitate connection of the Octave Temperature Control/Switch module. \nThe Nema 14 motor within the Up! Mini's extruder head generates excessive heat when handling large projects, necessitating a solution that ensures smooth operation. A high efficiency fan was installed adjacent to the motor, expertly crafted from repurposed electronics components.\nTo create an air conduit system for efficient airflow, the design incorporates a duct/casing unit. This housing securely attaches to the stepper motor with four strong neodymium magnets (6mm/0.2" diameter), allowing effortless detachment via simple disconnection of the JST connector.\nThe integration proves lightweight and entirely functional, boasting flawless performance.\n\n \n \n Assembly Instructions\nA print resolution of 0.25mm at moderate speed and a modest infill density of 10% accompanied by three layered builds proved to be the optimal settings for this part. The design is perfectly suitable for rafting with minimal support requirements, although some printers may necessitate adjustments in these settings.\nMagnetic Mount Installation\nFor attachment to the stepper motor, secure mounts have been designated for four small neodymium magnets of 6mm (0.2") diameter each. A straightforward gluing process facilitates an unshakeable bond between magnet and holder. In contrast, the lower mount necessitates mere sliding motion into position with no gluing required.
