Mounting Bracket for esteevens' Fan Duct to fit rp3d Pangu Wooden i3

thingiverse

This is a 3 part bracket to fit esteevens' fan duct on my rp3d Pangu Wooden i3 printer which originally had a standard 40mm unducted fan mounted forward of the extruder. Should be fairly self explanitory how it fits together, M5 screws self thread into the main bracket and the circular top section of the drop-link. The fan is screwed to the drop-link with an M4 screw and nut, the nut fitting into the recess on the back of the drop-link to stop it turning. M3 screws attach the main bracket to the extruder mount. Position the horizontal arm fan and drop link as necessary to get the duct in the right position. Don't forget about clearance at the far of the X axis. I found it necessary to tweak the duct slightly by using some hot air where the ring connects to the blower and putting a slight bend in there to lift the end of the ring up so it's uniformly level and above the bed when mounted and extruder is at the Z-stop.
