Davinci 80mm fan exhaust

thingiverse

Mounts into a hole on the side of my davinci printer, mating seamlessly with an 80mm fan. Part2 securely attaches the other side of the 80mm fan to the flexible duct. I'm sorry if this design looks slightly askew - it was actually my very first creation! To achieve optimal results, use a 4" duct that resembles this one: http://smile.amazon.com/FO450-5-ply-Supurr-Flex-Aluminum-Ducting/dp/B00009W3H2. I've used reliable hose clamps like these: http://smile.amazon.com/Spectre-9704-Hose-Clamps-Pair/dp/B004AJ352W. Instructions To achieve ideal results, I printed mine at a depth of 0.2 and 20% infill. To avoid overheating my external components, the fan runs on an external 12v power supply. In addition to controlling the fan, my arduino/relay combination regulates an rgb LED strip that's situated inside the case (check out below for more information). I've integrated a switch that notifies me when the Y axis reaches home position; the extruder won't move until this condition is met. Doing so has completely eliminated any chance of running the fan during the heating phase and getting the dreaded error 0010, which signals that my bed isn't heating as rapidly as it should - I'm literally pulling cold air over it. This little problem was eradicated with arduino control waiting to turn on until after the extruder has finished its movement. I utilized some insulating foam to seal off the top opening, keeping it user-friendly and easy to open: http://imgur.com/a/xt6pe. The primary component is cut out from a tube of insulating foam with gorilla tape, whereas I've employed weather seal foam to block smaller crevices on the sides. Upon implementation of this feature, my entire room is now odor-free thanks to running this system; what an absolute essential! To further enhance my experience with using fan controls and color manipulation with arduino code. 3 Transistors were used each for the red, green, blue RGB led lights. A servo also helps facilitate opening cardboard covers to assist dislodging any stuck pieces in place on these specific applications, along side controlling fan usage via small voltage regulators found typically located within home wiring.
