Makergear M2 Extruder Fan Duct
Description
This Is A Combination Filament Drive (Remixed From Rsilvers Super Filament Path Http://Www.Thingiverse.Com/Thing:267137) And Fan Duct. The Duct Takes A 40Mm Fan And Is Side Mounted On The Filament Drive. As Seen In The Images, I Rotate The Hot End Such That The Wires Extend To The Front Of The Printer To Decrease The Clearance From Fan Duct End And The Extruder Tip. The Filament Drive And Fan Are Connected With A Rod And Dovetail Joints. The Filament Drive Also Contains A Second Male Dovetail To Mount The Upper Cooling Fan. I Will Add That Design Shortly. I Printed Mine In Abs. For The Filament Path, I Scale It Up By 2%To Compensate A Bit For Shrinkage But Even So, I Still Have To Spend A Couple Minutes Working On The Drive With A File To Get The Hot End To Fit All The Way Back Into The Groove. I Also Run A 5/64 Drill Bit Through The Filament Path To Widen It Slightly To Prevent Binding.
