Oct 20, 2017 I had never played with the FR percentage on the CR 10 printers before. I knew if you turned the control knob you could change the normal 100% to be smaller or larger but never saw it make a.

This two piece part replaces and adds to the acrylic stock cover on the Creality CR-10's Z-axis lead screw; It lets you manually control the hot end up and down (when steppers are disabled), which I have found to be VERY handy at times. For example when you're loading filament, stopping a failing print or first layer, you can easily lift the hot end by hand to give you more working space and a better view of the piece.
I have now also added a bigger version. This way it takes less spinning to manually up and down the hotend. Easily fluently movable with just one finger. (09-15-2018)

If you want to use the ZKNOB on the Ender 3, you don't need the cover plate, as the Ender 3 has a loose lead screw. I suggest printing Ben White's stabilizer, which holds a 608 skateboard bearing and secures the top of the lead screw, so you can safely screw up and down without having to be extra cautious.
P.S. A filament guide is necessary to use the knob on the Ender 3.
FIX (02/10/2018)
Thanks to user wonkoderverstaendige I found out there was a tiny (but real) problem with the file of the big version. Basically the knob floated a mere 0.002mm above the stem, which only caused a problem when sliced in particular way, but it had definitely a weak spot. So if yours snapped at any point, this is probably why. You should have no problems with the fixed file anymore. Sorry for the inconvenience if it got you frustrated!

Pemic: 'The knob works also for the Tevo Tornado. The stock cover is not necessary. To gain a little space on the upper side of the spindle, you have to pull the Z stepper axle a little it out of the coppler.'

Fort_Design: 'I just wanted to let you know that this design will not fit the Anet E10. Mainly because the housing of the upper bearing on the E10 is closed on top. One would have to redesign these housings. Diameter of the spindle on Anet E10 is 8mm.'
