LCD Knob with a thumb sub-knob

thingiverse

We've all been there - the faulty knob that came with the kit just didn't cut it and vanished on the second day (or maybe night, my sleep-deprived brain can't be sure). I desperately needed something that would let me quickly adjust the print speed during those long night sessions, usually around 4 am when things get really crazy. That's why I added a finger-friendly knob to the existing one - now I can spin it faster and with less effort. If this modification works for you too, great! But if not, don't worry about it - no charge for the fill. By the way, feel free to adjust the Z-height of the knob as needed - its original size was a bit exaggerated due to the spool holder bracket being a tad too close.
