Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5241869.
Based on the Z-Axis Knob for Creality Ender 3 by guppyk (great design by the way). I included a direction arrow and text for up or down, just as a visual reference. Two versions are included, one with an up logo & arrow and one with a down logo & arrow. You may also want to use a bit of eclectrical/insulation tape to help afix to the z-rod.
Remember to give my thing a <strong>"like"</strong>, it´s very much appreciated :)
