Prusa i3 Fan Duct for J-Head & Wade - Improved
Description
This Is Still Just A Quick Variation Of Philsson'S 40 Mm Fan Duct. Http://Www.Thingiverse.Com/Thing:184055 This Time I Increased The Size Of The Duct A Bit, So There Should Now Be A Little Bit More Air Flowing To The Extruded Material. I'Ve Also Tried To Control The Flow Of Air Around The Nozzle A Bit Better. I Had Printed A Few Big Herringbone Gears For A Wade Style Extruder And They Came Out Distorted. Turns Out That Most Of The Air Flow That Is Directed At The Extruded Plastic Was Coming From One Side. I'Ve Blocked Some Of The Air Flow In An Attemped Distribute It More Evenly. It Seems To Work, The Distortion Problem Stopped. I'Ve Tweeked The Now 8 Mm By 15 Mm Opening To Help Provide Cooling Air Flow To The Peek Body Of The J-Head. The Theory Is That It Would Reduce The Chances Of Pla Jamming. It May Also Be Beneficial For Use With Abs, But I'M Not Using It With That Kind Of Plastic At The Moment. On The Down Side It Might Cool The Extruded Abs Too Much.
