Kuro's for Kossel

thingiverse

I'm really enthusiastic about the original Kuro's extruder, but there are a few things I'd like to modify. First, the large gear: you have to use a certain number of washers to elevate the large gear so that it lines up with the teeth of the small gear. I thought I could slightly adjust the large gear and no longer need any washers. (You could turn the small gear upside down on the motor shaft, but every time you open your extruder, you have to remove the small gear.) I've removed the PTFE channel from the 3/8" push fit since you can easily push the PTFE through the fitting, but I've left it in the E3D version. To mount it on my mini Kossel (15x15 version), I essentially used my original design mount and cut a piece out of it.
