DMK8 Bowden- The Dual MK8 extruder, Bowden version

thingiverse

Dual MK8 Extruder The Hobo (Cheap) Bondtech Extruder The Patent-Pending Core of This Extruder is the Power Transmission Using the Bolt Axle Who is Also Used for the Lever Arm. Bowden Version Changing One Part, You Go from Direct to Bowden. You Need to Properly Build, Assemble, and Test the Gears. I Designed This Extruder a Year Ago. Long Before I Even Knew a Bondtech Gear Existed in This Material Plane. Now I'm Publishing It in Two Versions: <a href="https://www.thingiverse.com/thing:2980133">Direct</a> and Bowden. It Uses Two MK8 Hobbed Gears, One of Them Who Needs to Be Put on a Drill and Sanded (Less Diamenter, More or Less You Need to Take 0.3-0.4mm of It). The Gears Need to Be Built Using Nylon. Don't Even Bother with PLA or ABS. They Are Press-Fitted. You Will Need Three 5x75mm Hexagon Head Bolts. Parts Can Be Done in Any Material You Like. Try to Avoid TPU or Chocolate. If You Want to Use 1.75mm Filament, Assemble It Without the MK8 Gears and Use a 2mm Drill Bit Where You See Fit. If You Want to Use 3mm Filament,... Well. You Get the Point. Printing the Nylon Gears: IT SUCKS. Yeah. Try with Horizontal Expansion Settings in Cura. Remember to Put Some Grease In. Assembly Instructions: https://a360.co/2lF1Nfi Open That Link, Use Your Brain. Gears May Be a PITA. Proper BOM Will Be Updated "Soon". Temporary "BOM": Shitloads of Strange Ball Bearings. This Thing Is Made to Last. Look at the Assembly Instructions. Three - Five 5x8x2.5 Six - Five 13x4 ABS or PLA for the Chasis. Nylon for the Gears, Two Big Ones, Three Small Ones. Print Shitloads of Them and Play with %Size and Horizontal Expansion. The Small One in the Stepper I Think Needs to Be a Bit Small. Mostly M4 Bolts. Two 55mm M3 Bolts to Grab the Filament.
