Direct Drive Extrusion (Extruder) @ Prusa I3

Thing DetailsDesigned around the J-head IVThis is the compact extruder that you've been searching for! Using a remixed X Carriage (link in description), I aimed to design a simple yet powerful direct drive extruder capable of handling even the most demanding filament pulls. It's exceptionally lightweight, resulting in reduced X stepper wear and tear.Designing around the J-head IV\nBOM\nLong metric bolts: M3 x 60 (2)\nRadial ball bearing: TYP. 608 (1)\nHotend: J-Head Mk V-BV link: https://www.hotends.com\nStepper motor: Nema 17\nFirm Spring: Approx. 1" long >6mm OD (1 or 2)\nBolts: M3 x 25 (8) \nPrinted\nDirect Drive Bearing Block (1)\nDirect Drive Block (1)\nThe J-Head Wedge\nUploaded 08-02-2016Update Inventor Screenshots 08-03-2016Update Printed Parts! 08-05-2016\nThe Print is Near!\nPrint Settings\nPrinter Brand: RepRap\nPrinter: Prusa I3\nRafts: Doesn't Matter\nSupports: Yes\nResolution: High\nInfill: 25%\nNotes: Will need a software that can produce support material.Post-Printing\nInclude this to your Prusa I3, to complete the assembly.\n Link: http://www.thingiverse.com/thing:1701003\nHow I Designed This\nDesign Aspect\nLooking at my bulky, old, and typical Wade's extruder printed poorly out of ABS - I desired something more. Something sleek and lightweight but still fully functional, of course. Using some parts that came straight out of my Wade's extruder, I designed this simplistic direct drive extruding system that would hide the Nema 17 mount bolts while leaving room for this excellent Y carriage mount holes, found right here on Thingiverse. This was actually the third iteration of design after many seemed unpractical or just dysfunctional.Designing around the J-head IV\nCustom Section\nFeedback is Important\nFeel free to leave a like, or comment.
