Smaller Emaker Huxley shaft coupling

thingiverse

When fitting shaft couplings on your Ender 3's X axis, be aware that they may collide with your hardware if they have a smaller outer diameter than the original ones. Despite this potential issue, these couplers are designed to provide full travel. To assemble them, simply press M3 nuts into the hexes and secure with M3 screws, just like you would with the stock couplers. However, it seems that they may not actually increase your travel range.
