In BikeCAD version 15 the option to make a 3 bolt pattern of water bottle bosses for the Salsa Anything cage was added. In version 17.5, we have even more flexibility with the option to add any number of single water bottle bosses for rack mounts or any other custom accessory such as bolt on frame bags. You'll find the single water bottle boss option among the choices of cages in the Water bottles dialog box.
