  1. The bowden tube connector needs  prepped before installation ; First cut 4.5 inches of Loctite tape. A link to this product is provided at the beginning of this guide. Then, cut the piece of Loctite tape lengthwise.
    • The bowden tube connector needs prepped before installation ;

    • First cut 4.5 inches of Loctite tape. A link to this product is provided at the beginning of this guide.

    • Then, cut the piece of Loctite tape lengthwise.

    • Now, wrap a single length of Loctite tape around your connector in the same direction as the threading

    • Now that the connector is prepped you can set it aside.

  2. Next we will prep the hot end for installation. Cut 4.5 inches of Teflon tape. Fold the piece of Teflon tape lengthwise.
    • Next we will prep the hot end for installation.

    • Cut 4.5 inches of Teflon tape.

    • Fold the piece of Teflon tape lengthwise.

    • Wrap Teflon tape around the hotend in the same direction as the threading.

    • As shown in the last image, now is a good time to set your thermistor (white wires) and heater cartridge (red wires) in place.

    • Slide the metal cylinder of you heater cartridge into the largest opening in our hot end. Center it so that you have even heating throughout. Once in place, tighten down a 2.5mm set screw on the side of the hot end to secure the heater in place.

    • There is a smaller hole adjacent to your heater cartidge, this is where your thermistor will go. Put a small dollop of thermal paste over top of the thermistor opening. Then slowly and carefully press your thermistor through the paste and into the opening. Link for thermal paste is at the beginning of this guide.

    • Allow the thermal paste to dry for at least 6 hours. We recommend you let it set overnight. Once it has had time to set check to make sure that everything is secure by GENTLY tugging on the wires. Do not pull on them too hard, they will pull out.

  3. Screw cold end to the hot end until the Teflon tape is no longer visible. Note that the cold end should not be touching the flanged edge of the hot end. For now keep a couple millimeter of space between the two. Insert the white extruder insert (aka nozzle holder) into the cold end making sure that the funneled end is facing away from the hot end. See 2nd picture. Push the extruder insert down into the cold end until it touches the edge of the hot end. Use your calipers to measure the depth of the insert. You want to measure from the top of the white extruder insert to the top edge of the cold end. Continue screwing the hot end in until the insert measures 4.43 mm from the top of the cold end.

    • By tightening the hot end you will in turn be raising the extruder insert.

  4. Attach bowden tube connector to the cold end, so that it's finger tight Tighten bowden tube connector lightly with wrench, making sure not to over tighten. Over tightening will compress the insert and prevent proper extrusion. However under tightening will also cause problems because it will allow gaps where filament could ooze into. Look through the bowden tube connector, and you should have a clean unobstructed  path to the nozzle. See picture 2.

    • Look through the bowden tube connector, and you should have a clean unobstructed path to the nozzle. See picture 2.

    • Filament should slide easily all the way through to the nozzle.

  5. You now have a completed nozzle
    • You now have a completed nozzle

    • Enjoy your printing

Hi, can you tell me what the diameter and thread of the pneumatic fitting for the bowden tube is? I think it’s an M10-1.0 but would love confirmation.
