Geeetech Aluminum Prusa I3 Floating Z Axis

thingiverse

It's a major challenge to get the z-axis threaded rod perfectly centered in the couplers included with the kit. To overcome this hurdle, try mounting the threaded adapter to this component instead of directly attaching it to the z-axis carrier. This setup allows the z-axis carrier to float on the threaded rod, significantly reducing the wobbling caused by a crooked or off-center threaded rod. This revised version requires an additional 8mm of vertical clearance below the carrier and above the coupler, which may cause problems if the coupler isn't sunk down as far as possible or if centering couplers are used. I'm already working on another revision that would recess the thread adapter further into this piece.
