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

3D model description

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!

A simple quick and dirty demonstration by me of how the knob works:

And a more professional video by Chuck Hellebuyck on how to install the knob (and some other useful CR-10 (mini) mods) on Filament Friday: (3 minnutes and 23 seconds in).

3D printing settings

Creality CR-10



0.2 mm


Print the knob upside down. No supports needed.

Pictured parts are printed in Das Filament PLA at 190°C/50°C on the Creality CR-10. You can probably go lower but I printed the with a 30% infill for extra strength.


Just swap the acrylic stock part with the freshly printed cover plate, using the stock screws. The knob then simply screws onto the lead screw until it's snug enough to let you control both up and down movements with it.

I am Baschz, an artist and designer from the Netherlands with a profound love for hand made things with a mass production look and feel to them. 3D printing gives me the possibility to by hand create small run (art) projects that look like they we're pooped out by the thousands in a factory far far away. You can find some of these products in my Etsy shop. I also use 3D printing in other work and to fix or upgrade things around the house or on my printers.
