Bondtech BMG + E3D V6 print head for Creality CR-10(S)

thingiverse

Update Oct 4, 2018: Modified design of the body to make thin parts at the bottom stronger, added an optional support for attaching a BLTouch sensor. This support is offset from the nozzle by +32mm on X and -2mm on Y. The part cooling fan is now attached with M3 screws and secured better with two screws. This is my Bondtech BMG + E3D v6 Print Head, also known as "The Tank," used by my friend Tom Jackson (@FilamentFrenzy) on his Creality CR-10. All pictures courtesy of Tom Jackson. The fan shroud is from the Prusa i3 Mk3, modified slightly. There are minimal instructions here for assembling the print head. Do not attempt this modification if you're not comfortable tinkering with your printer. You won't lose any print volume with this print head provided that you move your Y endstop 8mm forward. You'll need: - A Bondtech BMG extruder (design is compatible with both right-handed and left-handed ones) - A NEMA 17 Pancake stepper motor (25mm deep) - An E3D v6 hotend - A Noctua NF-A4x20 FLX fan (40mm x 20mm) - The Noctua fan fits perfectly on the mount; you can use another 40x20 but will need to grind a bit at the top left edge of the fan for the head of one screw that holds the rollers - A 12V 50mm x 15mm blower fan And also these screws: - 2x M3x20 socket head screws (to attach the blower) - 2x M3x8 flat head screws + 2 M3 washers + 1 M3x6 socket head screw (to attach the rear body to the X-carriage) - 4x M3x25 screws (to attach the Noctua fan) - 2x M3x20 socket head screws (to attach the front and rear body together) - 2x M3x6 socket head screw to attach the fan shroud The design is fully compatible with Prusa's new 45° fan shroud. A few quick notes: Simplest way to do wiring is to use your stock hotend, cut wires (hotend fan, part cooling fan, thermistor), and reconnect them to the new fans and thermistor. If you use 2-pin male-female dupont connector for something dismountable, the "Stepper spacer and cable holder" has a space to hold them securely with zip ties. You can re-use the stock heating cartridge. The hotend fan's cable is routed in a trench on the rear of the read body; you need to install this fan before attaching the Body - rear part to the carriage. The part cooling fan's cable is also routed through a cable way through the body. You'll need PTFE tube between the E3D hotend and the Bondtech (Capricorn tubing recommended if you have some).
