Adjustable Z endstop for the Ender 3

thingiverse

This is an adjustable Z axis endstop designed specifically for the Creality Ender 3, making it easier to adjust the bed height when your bed is already level. Hardware Requirements: 1. One M3 x 40mm countersunk screw 2. Two M3 nuts 3. One M3 washer 4. The original bedspring (the soft spring you've replaced with stiffer springs) 5. And also, the original hardware for the switch bracket Instructions: Print the "Base" standing upright or upside down. Print the "Slider" lying on its left side to achieve vertical layer lines for smoother operation. Print the "Wheel" upside down. You may need to sand the parts for a good fit depending on your printer's specifications. Glue a nut inside the "Slider". Mount the switch with original screws, place the spring on top of the "Slider", and slide it in. Then, mount the "Base" using T-nuts and screws from the original bracket. Put the M3 screw in the "Wheel", add a nut to the underside, and a washer below the nut. Screw it into the "Base". Using some grease can ensure smoother operation. If you try this out and find that it lacks sufficient adjustment range, please let me know so I can make adjustments or create alternative parts tailored to your specific Ender 3 setup. For users with lower bed heights, consider using the short version of the slider.
