CR-10 Z-Axis Manual Adjustment Knob & Lead Screw Cover

Last crawled date: 6 years ago

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)


FIX (as of 02-10-2018)
Thanks to Thingiverse user wonkoderverstaendige I found out there was a tiny (but real) problem with the file of the big version. Basically the knob floated 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!
