There are computer aided processes that can manufacture items such as that - things that can be made an a lathe. Such machines are very expensive at this point, however, such as the equipment made by Herbert Arnold of Germany which runs well over 100k. I would love to see some lightweight, less specialized automation in this niche, as what currently exists are heavy duty CNC class machines. They are impractically expensive and overqualified for projects like 20g tubes of glass with one end closed and a ridge.
