Minimal Dual Fan Duct (4020 Radial) Flsun Prusa I3 2017

thingiverse

This is a compact dual fan duct (MDFD) engineered specifically for the 4020-type radial fans. It was designed to seamlessly fit the Flsun i3 C (2017). The ducts effortlessly slide into place within the fan's opening and do not require any additional attachments. The mount also permits both fans to be easily rotated out of the way when part cooling is not needed. In my setup, they can be quickly disconnected through terminal block connectors located on top of the extruder carriage. These ducts can be printed even if you haven't installed part cooling yet. Simply print one side first, install it, and use it as a guide for the second one. Hardware Requirements: * 1x M3x25mm * 1x M3x30mm * 2x M3 Hex Nut Fans Needed: * 2x Radial Fan (4020) Parts Required: * 1x Printed 7mm Spacer for the left fan * 1x Printed MDFD_4020 Mount (or another designed to fit your printer's specifications)
