CNC Fan Mount for laser engraving ( 1610 / 3018 / 2418 )

Description

Using Tinkercad I Designed This Thing To Connect An 80Mm Fan To My 3018 Cnc So I Can Evacuate The Smoke From Laser Engraving Up 3" Flexible Ducting I Purchased At Home Depot To The Ceiling Exhaust Fan In My Man-Cave (Or You Could Just As Easily Stick The Exhaust End Out A Window). This Allows Me To Engrave Wood Right At My Desk With No Smell Or Smoke Issues. I Believe The X/Z Carriage Is The Same For The 1610/2418 And Possibly Other Cheap Chinese Cnc Machines As It Is For My 3018 So It Should Fit These Other Machines. The Frame Snaps Over The Mounting Spacers Holding The Z Axis Stepper Motor, It Is A Tight Fit But There Is A Clip At The Back For A Cable-Tie Just To Make Sure It Doesn'T Come Off If Something Interferes With The Duct'S Movement During Engraving. The Angle Of The Fan-Frame Is Adjustable With Notches Integrated Into The Joint To Lock It Into Place. The Plastic Bolt May Not Survive The Test Of Time But I Didn'T Happen To Have A Long Enough M5 Bolt Lying Around (60Mm Min). This May Need To Be Replaced With A Metal Bolt And Wing Nut/Printed Nut At Some Point. There Are A Couple Of Funky Corners, This Is Just Me Learning How Best To Handle Rounded Corners In Tinkercad, I Needed This Fan Finished So They Have Been Officially Categorized As "Good Enough" :) This Works With My Eye Protection Thing: Https://Www.Thingiverse.Com/Thing:2984605 If You Need To Adapt To Flexible Ducting Of A Different Dimension I Recommend: Https://Www.Thingiverse.Com/Thing:1015874
