Aloha's MiltyKoss Stepper Duct (Fits Mini Kossel and similar size deltas)

thingiverse

Mini Kossel and similar size delta printer stepper fan duct. Fits 120mm fan for silent effective airflow using my standard 120mm 3-screw mod bracket. Shown with a variable resistance dial to adjust RPM installed in place of the auto-adjusting thermistor it came with (which was set to who knows what temperature). I leave the electrical up to you, but research what you want to do with your fan and proceed at your own risk. The fan wires can pass through the mod bracket and be plugged in without modification. Simply cutting the fan frame away except for the hub and using the preexisting wiring uncut is the easiest method, sourcing a fan with a speed adjuster pre-installed providing the simplest control. Wires can come loose though, use caution to protect you and your delicate printer electronics from loose wire shorts.
