This is a quick mod of the High Resolution Herringbone gears for Greg's Wade Reloaded extruder. Specifically the small Herringbone gear that attaches to your stepper motor on your extruder. I've been having some problems on my Homemade/ Homebuilt Lulzbot Mini with what i thought was heat creep, but which may have been a clogged nozzle. At the same time this little gear keeps coming loose and could be contributing to my printing problems. Therefore i have made a small mod for it to have two set screws placed 90 degrees from each other. This in theory should help a lot. I'm surprised it was not designed this way to begin with. Enjoy.
I have yet to print it and test it, but i will soon. I will try to upload a photo when i do. Until then i will publish this early like most of my designs and thingiverse uploads.
