Wanhao Duplicator 6 Air Inducement Duct

thingiverse

I tried printing an air induction shroud for the Duplicator 6 but it was far too thin all over and square in the channel profile, which doesn't seem good for airflow. It was also relatively fragile during removal and Slic3r hated it. I think I'll try printing another one and see if that works out better. I'm still unsure if my previous design actually worked because I should probably use the latest version of Cura to see if it freaks out and makes walls too thin. So you get to have my DFAM optimized version of the Son of Air Inducement Duct, which has thick overengineered walls so it doesn't disintegrate when you try to remove it from the bed. This design includes a tiny little divot that connects the gap at the opposing end so the thing isn't SO FRAGILE as to fall apart after you lift it off the bed. It also has nice, round fillets everywhere so your machine won't have to slam on the emergency brakes and make maximum instantaneous acceleration in another direction. A "stop drooping when I try to bridge a tiny little gap" feature is included in the middle of the area where the fan is supposed to mount*. Extra thickened structure is also added because that tiny square profile cannot be the answer to airflow. Instead you get a nice tubular channel that resembles a P in profile for the downward channel component. I've mentioned the whole rounded, filleted all over thing that seems to help with printing it as well as the round cross section for airflow. And with any luck, you will probably see a new version of this design (eventually™**) that actually OFFSETS the fan so its not trying to suck air from an area that has a plate and cavitate like a drowning adult. A full disclosure: I don't claim to know anything about thermoprinterfluidnomics. I just had some real personal issues on a miserably humid and hot day in trying to get a better fan shroud that doesn't require me to find and buy a new fan then print a new shroud so I put my energy into making a clean room "derivative" that solves my personal issues. You will lose a little bit of print area in the left corner (Perspective: You facing the printer) if you use these ducts, they will bump the motor. They effectively take about 1 inch/2-3cm, as in the legs of a triangle more or less.
