It's a Vertical X-End designed for custom builds and minimalistic New LM8UU Version Added the X-Carriage Default files are 22mm, there is also 30mm Files for standard Prusa. You can ask for another spacing for Z if you have a custom build. Specs Print & Use !PS: Carriage And Minimal direct drive extruder come soon.
