40MM Fan duct for MendelMax & Prusa V3
by Ultibots
Description
This duct takes the good 40mm Fan Duct V3 from Ultibots and optimizes it to not require printing supports, and to evenly distribute the cooling flow across the width of the gap. It also gives more directed flow toward the printed parts at the end of the print nozzle.
Instructions
Print without support. I printed mine at 0.20 mm on a 0.35 nozzle. 3 perimeters and 3 solid top & bottom layers.
The fan mount is taken straight from thingiverse.com/thing:34387.
The fan mount is also the belt clamps.
18 March 2013 - Note: I have sized the holes that mount to the fan to be tapped for an M3 bolt so it does not need a nut. These holes have a 2.5 mm diameter, so if you want to use a nut to hold your fan on, just drill them to the diameter you need.
