Parametric Carriage Base for V-Slot Printers

I originally designed this openscad script to be used with my Emmett-Delta 3d printer that uses 2060 V-Slot for the Vertical columns & 3/4" EMT for the horizontal supports. I took some extra time & made this parametric to facilitate changing it for different configurations. It looks kind of like a dog bone in this setup, but you can change 17 different variables to make it in almost unlimited configurations. The carriage that holds the belt and rods is a separate file, so you can use your own
