I can guarantee that it will be cheaper to just buy a clawfoot tub, or a 3 tap kegerator for that matter. 3D printing a clawfoot bathtub that big will cost thousands to tens of thousands of dollars, and misses the point of 3D printing. 3D printing is not cheaper than conventional mass produced items, and won’t be for at least another decade or two. The value of 3D printing today is primarily prototyping things that don’t already exist, or making things that can’t be made any other way (i.e. a ball inside a ball), or customizing something for a specific reason (custom fit prosthetics.)
