🔧 Genuine E3D Hobb-Goblin V2 - 5mm Internal Diameter Drive Gear (M-HOBB-V2-50-0-BORE) Review

There is only one, but it is good, so in my opinion there are no complaints about the quality. At least they took a better picture.

Like it had sharp drive teeth Arrived on time Doesn't seem expensive Used on a Pitan/Ender 3 extruder Set Pitch E to 420 When filament gets stuck, hobbGobblin chews it up.

They look great but don't work with MK8 extruders. They're just too small. Due to the diameter of the drive gear, the toothed disc has to go too far and get caught.

I installed this in a Wanhao i3 direct drive extruder. With the stock gear I had extrusion issues because the motor didn't have enough torque to push the filament smoothly, especially when I widened the line. With this smaller mechanism, I had no issues with stripping or under-extrusion. He pushes the thread and the thread moves. This gear is a good option for those suffering from chronic underextrusion. My only complaint is that the $15 price tag seems high for a small device, but I get a lot…

Very similar to imported MK8 but MAN is not the same. The thing is the best in the world. Noticeable improvement in print quality. The cutter diameter is about 7.62mm (the imported ones I have are closer to 7.25mm). It's a bit larger than the stock gearing on the MK2, but I've heard people use it for this without having to modify the extruder body. Not sure how this is possible as I had to modify the body to fit the import which is even bigger but *shrug*. Lots of people do this. I don't have…
