Radial Fan Fang

thingiverse

Human: Does your layer fan focus a sphere of air precisely on the sweet spot?\ncheck out the video test below (using radial fan 4020) for aerodynamic results and then test yours to see if you're using all the air output, or just part of it.\nThere's an interesting video for high-speed printing tests to compare four fanduct models including this one done by ruiraptor: https://www.youtube.com/watch?v=c0llj3pBltA \nSource code included (blender files, .obj).\nSupport:\nHotends:\nE3D\nE3D Titan\nTevo Stock (chimera single nozzle)\nRadial Fans:\n4020\n5015\nSensors:\nNo sensor\nLJC18A3 (Set X: +49mm, Y: -19mm)\nLJ12A3 (Set X: +49mm, Y: -19mm), it'll fit in LJC18A3 18mm hole, the nuts are bigger\nBLTouch (Set X: +39mm, Y: -21mm)\nSN04 (Set X: 39mm, Y: -8mm)\nFeatures:\nThe fang design lets you see what's going on while printing, so you can reach and remove oozing before it ruins the print.\nThe very efficient air blow has minimal curves and no hard angles to avoid air collisions.\nSPHERE air concentrating!!! all air is blown focused on nozzle tip, then gets reflected in all directions (see the video).\nThe adjustable height ensures a perfect fit for your own configuration.\nBalanced air distribution blows from two sides against each other; the air escapes from the other two sides, with no pushing from one side only.\nAlso, Radial fan gives more air on one side of its output hole, and the perpendicular plugging design splits the air current equally for each tube.\nCompatible with E3D, Tevo Stock hotend, and many others (please comment if yours fits too).\nSupports both 4020 and 5015 Radial fan models\nLED holder, very recommended; huge lighting focus, even in dark environments\nHelp:\nWhich file to print\nThere are two main models: Radial Fan 4020 (40 X 20 mm) and Radial Fan 5015 (50 X 15 mm).\neach model has four versions to support all sensors.\nIdentified by the file name as: Radial Fan Fang [Size] [Sensor].stl\nExample: if you have a radial fan 5015 and LJC18A3 sensor, then print:\nRadial_Fan_Fang_5015_LJC18A3.stl\nNote that this design must be mounted on a 3mm hotend fan; if you have a 40mm hotend fan, take a look at remixes.\nYou might find the best fit for your printer there\nPrinting Tips\nAdd brim support if the first layer doesn't stick well.\nyou need to add printing support for sensors edition; select the proper support type so you don't add support inside.\n40% infill is recommended due to sensor mount.\nIf you don't have a layer fan before and couldn't print without one, make a quick temporary setup with your radial fan (cardboard & duck tape).\nto get the first print with poor quality, then install it and print a better one\nInstalling\nAdjust the height to make the hang tips higher than the nozzle tip by 2 to 3mm.\nIf you have a sensor, set X: +49mm, Y: -19mm\nBLTouch (Set X: +39mm, Y: -21mm)\nSN04 (Set X: 39mm, Y: -8mm)\nThe fang design lets you see what's going on while printing.\nAdd brim support if the first layer doesn't stick well.\n40% infill is recommended due to sensor mount\nPost-Printing\nHow I Designed This\nDesigning this fanduct was a challenge, but I'm happy with the results.\nI designed it in blender (get it free from www.blender.org)\npress 3 on num pad, to go to front view\nright click on the fang, to select\npress tab key, to enter edit mode\npress z key, to show all points\npress and hold ctrl + left mouse key, to select points\npress z key, to go back to solid view\ndrag axis, to make the wanted adjustment\npress tab key, to exit edit mode\nselect all parts by right click & hold shift\nFile > Export > .stl, then check "selection Only" then Export STL
