This is another r3 style hotend mount. it is a work in progress. everything works, I use it in my current build. It does not have a place to mount a bed probe. I don't currently use one. In the future I plan on adding a place for an ir probe on the carriage along with the x limit switch. I would like to also figure out better cable routing. Should work with the standard hypercube evolution carriage. I have included the carriage I use with it. This carriage uses 10mm ID Long style bearings or you can fit the short bearings side by side. There is no length limitation of the bearings. I included a step so you can mod this to fit your own project.
