Wanhao Duplicator 6 Offset Fan Air Inducement Duct

thingiverse

If you liked my air induction duct, I forgot to release this version which has the same offset fan configuration as my later designs. I went with direct cooling for the intense amount of directed airflow in those later designs and have been sticking with that since then. This is just something that I didn't release after making that jump. For anyone confused about the offset fan: Imagine if I put a shopping bag with a tiny hole at the top of your hair and asked you if you liked breathing more or a compact fan and air duct configuration more. Somewhere, I should add that I start pouring water over your head, but that's a metaphor for hot plastic. I promise there won't be a wet towel over that plastic bag in that process. I'm more than sure the fan doesn't like being there with the lack of clearance. You could also read all the other summaries on my later air duct designs. You may or may not see a comeback for these designs, possibly with some direct cooling designs that use air entrainment on the nozzles to deliver a greater volume of air at reduced velocity and pressure. Otherwise, the other option is to have a tighter ring and most likely a centrifugal blower to create a compact air column around the nozzle. Ugly prototype and uglier lazy photo included so you know I actually do make and test these things before publishing them instead of insulting your intelligence by going "trust me, just test this and let me know if I should silently delete it and pretend it never happened" all while lazily pumping out designs in CAD for some kind of weak mental brownie points thing. Also, I forgot which one I used, my 14mm or 13mm standoff. Have fun with both files! If you don't know what they're for and can't figure it out, look at my other duct "The Magnum" for an image of how they're mounted. If the 13mm is too short, just start a print for another one and stop it as its printing the first few layers (Depending on how thick it is). If the 14mm is too tall, I hope you enjoy sanding. A warning: You will lose a little bit of print area in the left corner if you use these ducts. They will bump the motor. They effectively take about one inch or two to three centimeters more or less. Obviously, you have more to lose if you stick something like a heatsink onto your steppers.
