Creality Ender 3 Extruder Arm with screw tensioner (Improved)
thingiverse
I've updated my design based on the original thing from https://www.thingiverse.com/thing:3685539. To improve the overall functionality, I've added an extra holder to the idling wheel. This modification addresses a common issue where the extruder becomes tense after some time, causing the bolt to bend along with the idling wheel and resulting in skipped extrusions. Please note that you will need a longer M4 bolt for this updated design. A 10mm length is ideal to ensure optimal performance.
