Vortex Z Knob for Creality Ender 3

thingiverse

This is matching Z Knob to the Vortex Extruder Knob (https://www.thingiverse.com/thing:3518099)\r\n\r\nMatching this knob to the Vortex Extruder Knob will help spin the Z axis rod, raising and lowering the X gantry to check your nozzle. Most of the time you'll be raising up, so the claws on the knob are designed to spin it clockwise.\r\n\r\nI printed this in PLA with a filament change to get the 2-color knob. You can certainly print it solid in one color if you prefer.\r\n\r\nTwo versions are included: normal and extended. The Extended version gives more clearance over the top brace, while the normal one is ideal for keeping your filament holder up top and needing to clear the knob.\r\n\r\nThe threads on this knob are kept fairly deep, allowing you to screw it to any length you want. To prevent the knob from screwing further than desired, stuff something in the cavity.\r\n\r\nI've also kept the thread tolerance fairly tight to prevent the knob from getting loose and unscrewing itself. If too tight to screw on, try heating up the tip of the Z rod with a lighter and then screwing the knob on - this will "heat set" it into place, ensuring a perfect fit.\r\n\r\nGive it a try and see how it works for you.
