Ive started working on my little printer a long time ago and have some time to upgrade it some more, i have a Prusa Mendel and have been looking to upgrade to a vertical x-axis so i could switch out extruders quickly. I'm now wondering if the Prusa i3 x-axis would work ?? Any info or suggestions is much appreciated.

Thank you.

You would have to check if the x-ends of the Prusa i3 would fit on your z-lift geometry.
Or design your own X-ends.
