Linear Rail Gantry system

thingiverse

This work in progress features a linear rail system comprising a shuttle and rail. The rail boasts two V-grooves for the shuttle's V-groove bearings, along with a linear rack for meshing with the shuttle's gear drive system. For flexibility, rails can be connected end-to-end. Propelling the shuttle is a stepper motor, moving along the track via gears. With further refinement, this design could become a versatile 3D system applicable to 3D printers, laser cutters, and light CNC milling. Impressively stable, the shuttle's V-bearings glide smoothly in the track; additional bearings may be added for heavier loads. Please remember that this is a WIP, and vertical printing is recommended for best resolution. Don't forget to print eight bearing halves for the four V-bearings.
