Slice Enginnering Mosquito Magnum Semicircular Fan Duct - Direct Mounted

thingiverse

This mount demands that you swap out the M2.5x16 bolts standard for the hot end fan with M2.5x20 bolts to reach the threads through the duct arm and the fan. The stock bolts can then be reused on the opposite side mounting arm. The fan duct uses a 5015 radial fan and is directly attached to the Slice Engineering Mosquito/Mosquito Magnum. Ducting holes have a slight downward chamfer designed into them, ensuring that air flows onto your part rather than the heater block. This means you can use it on bowden or direct drive systems without worrying about carriage design or mount system interference. Almost completely universal, this duct fits any printer perfectly! No more searching high and low for a mosquito duct! I printed mine with resin on my Elegoo Mars but it should work well using PETG/ABS/Nylon on fdm printers. Just be sure to set supports to bed only to prevent your slicer from creating supports within the duct itself. This duct was derived from the part cooling duct here: https://www.thingiverse.com/thing:3613113 although almost no part of the original remains outside of the semicircular portion and fan attachment flange, after adjusting almost all other aspects to fit my needs.
