Removes the need for "h_lip" within that function. Significantly reduces the number of operations. Which is helpful when importing to FreeCAD. Future Work: * Convert chamfer calculations to functions. * Use those functions to replace "h_lip" with a calculated value. * Genericize chamfer code to a module.
