hob gobbler 3d models

The filament was not aligned with the M8 hobbed bolt and was bent. I put it back where it belongs. - I added a flexible filament guide in both 1.75mm and 3mm versions, complete with embedded support (carefully remove it after printing). - I...

##Requirements - Body/Idler - 1 x NEMA 17 Stepper motor - 1 x Heatsink for Nema 17 stepper motor (optional) - If you printed the body with PLA filament, it would be better to attach a heatsink - 1 x MK8 drive gear - Outer diameter: 9mm - Length:...

When mounting, you'll probably want to loosen the hobbed pulley/gear attached to the extruder stepper motor to ensure it aligns correctly with the directed filament guide. The directed fan mount and receiver are sized for the hexagon hotend, but...

Moved the filament path in middle part down and towards the back to interface with MK8 hobbed gear better. Moved length of moment arm out from 14.5mm to 20mm. Change spring pre-load from 2mm to 5mm. This also allowed for the arm to be thickened from...

Also- Decide if you want it to cover the WHOLE top, or if you need an opening in the back for accessories like a HOB filter, etc. If you do, just choose side pieces that are shorter to allow for the opening. 3) Print the parts. You can probably...

I suppose that these waves are dependent on the quality of the worm gear and the way they are made ("precision casting", hobbing, forging, whatever). So despite the fact that I cannot offer a real solution yet(?) I publish this second version,...

Here are some essential components you'll need to build your own custom X-carriage: * 3 x 24mm LM8UU bearings or 24mm Igus Drylin (you can find those here - this is a requirement for the X-carriage) * 8 x M3 Nuts (not locknuts) * 6 x M3-18 screw * 1...

Extruder: Pitan parts adjusted to fit 5x14x5mm bearings for the hob, and a 4x13x4 grooved bearing on the lever, plus a new 5x14x5mm bearing on the motor shaft for the lever. Optional Pitan body parts with holes for airflow. Suggested to mount with a...

• Universal "Bowden-Extruder - Material-Feeder", suitable for filaments with a diameter of 3mm, 2.85mm, and later 1.75mm.• Based on the conventional unicycle-principle: Suitable for a variety of knurled and hobbed drive wheels.• Finely...

(Also contains STL files, as I'm mostly changing existing stuff...) **Design changes:** o changed X and Y Axis idler to a standard M3 GT2 belt idler pulley o added stops for the rods of X and Y axis, also ZMax clamps, so they dont move when not...

There are two gears that will fit the steppers used, the MK7 and MK8 hobbed drive gears. Both will provide improved performance from the straight tooth drive gear, but the MK7, being smaller will provide the greatest torque. When you change the size...

Or it will try to push against the flat side of the gears rather than in the hobbed grooves! Grab a piece of Teflon // PTFE tube, preferably 1.9mm ID or lower than 2.0mm ID (I use a Capricon clone; it's okay, not really 1.9mm, but 2.0mm tubes are...

It is well designed and the dual driven hob pushes filament like no other. There are 2 versions of this mount. One that uses ball studs and another that uses SeeMeCNC nylon barbells, and should work with the machined aluminum barbells available from...

the gears are hobbed to match the filament shape and theirs 2 griping both sides vs a smooth pulley. they also have a gear box and massive torque they allow lower print temps and even extrusion/ stable flow singe random under extruded lines on...

# Introduction Remote direct drive extruders like the Flex3Drive (and its clone the Zesty Nimble) use large reduction gearing at the toolhead side to keep high torque from the extruder hob off the flex shaft. This has a side effect of seriously...
