Ender 3 extruder tensioner
thingiverse
This is a custom extruder tensioner designed specifically for the Creality Ender 3. To assemble it successfully, you'll need to apply superglue to a thin M4 nut and attach it to the bearing screw. For optimal results, print this part at 100% infill to ensure its structural integrity. I've personally printed this tensioner and found it to be functional, although not entirely flawless. The final photo shows the original extruder tensioner for comparison purposes.
