Creality Ender 3 Y axis clearance adjuster

thingiverse

I'm attempting to create a better Y-axis guide for my Creality Ender 3 printer. To achieve this, I've successfully converted from four bearings to three and made the clearance easily adjustable without needing an excenter adjustment. One possible reason for excessive wear on the Y-axis rollers is that they're using four bearings instead of the more self-stabilizing configuration with three bearings. To complete this modification, you will need: - A long M8 screw to serve as the actual adjustment mechanism - Two additional M5 screws of sufficient length - Two M5 self-locking nuts for secure fastening - Two 5mm diameter washers for added support With these modifications in place, adjusting the Y-axis clearance has become extremely straightforward. My printer is functioning flawlessly with this setup. I recommend securing the adjustment screw with an additional butterfly nut to prevent it from coming loose during printing. Please be advised that you're using this design at your own risk. I won't take responsibility if this configuration causes any damage to your printer. In this revised version, the M8 thread has been directly integrated into the fixed bearing block with the assistance of the excellent Metric Thread Library available on Thingiverse (https://www.thingaverse.com/thing:311031). Additionally, the fixed bearing block has undergone a material reduction for improved lightness.
