PowerFlower Geared Extruder
Description
**10 MAR 2020** The design has been updated with the following changes: - Support flexible filaments whilst being easier to print. - Replaced dual tensioner springs with a single M3 bolt for easier adjustment. - Remixed with the [PowerFlower Belted Extruder](https://www.thingiverse.com/thing:4214316) **04 FEB 2019** The PowerFlower is now parametric and available on Fusion 360: http://a360.co/2W1MYH2 The herringbone gears were generated via [Parametric Herringbone Gears](https://www.thingiverse.com/thing:818003). **Introduction** The PowerFlower is a geared Bowden extruder with a 4:1 gear ratio, designed for 1.75mm filament and an 8mm Hobbed Shaft. In the makefile I have generated and included the main and rear bodies for shafts with common effective diameters. Measure and print the correct parts or change the parameters in the F3D file. The other parts do not change! - x-body-175-60 - For 1.75 filament with 6.0mm shaft ED. - x-body-175-65 - For 1.75 filament with 6.5mm shaft ED. - x-body-175-70 - For 1.75 filament with 7.0mm shaft ED. - x-body-175-75 - For 1.75 filament with 7.5mm shaft ED. The design is semi-modular. There are two additional M3 holes in the front body of the extruder which will allow you to mount whatever you want e.g. a filament cleaner. **Background** I originally designed the PowerFlower for use with the E3D Cyclops Hot-End which requires a pair of geared extruders due to the 90deg bend in the filament path. I opted for the E3D Hobb Goblin 8mm Hobbed Shaft but because all of the Gregg's Wade's derivatives require supports and the Hobb Goblin protrudes significantly from the front I decided to design my own. After moving over to Fusion 360 I parameterised it for all hobbed shafts. **Components** 1x M8 Hobbed Shaft (I'm using the E3D Hobb Goblin) 1x NEMA17 Stepper Motor 3x 608ZZ Bearings 1x PC4 M5 Pneumatic Coupling (2x if you want a Bowden inlet) 1x M8 Self Locking Nut 1x M8 Washer 2x M8 Standard Nuts 3x M3x25mm for the rear body and idler 4x M3x10mm (or 8mm) for the stepper. 1x M3x12mm for the Tensioner. 4x M3 Standard Nuts 2x M3 Flat Washers for the Tensioner. 1x M3 Pozi-Pan for the small gear setscrew. **Final Points** As of the release date the PowerFlower has over 100h of printing time and I've seen no degredation in performance. If you're curious I have the following Marlin settings: Retraction speed: 80mm/s E Jerk: 5.0 E Accelleration: 1000mm/s I will be releasing a mount for a filament cleaner and gear guard in the near future.
