the plastic tubing in just about every tube case made is extruded. this means it has been made by forcing molten plastic through a steel form and then allowing it to travel through water to cool it.
most of the time anything other than standard round sizes found in the hardware store have have a special mold made for them. you can certainly browse through the websites of plastic extruders to see what types of forms they offer without having to maske a mold. but there is often a minimum order that is more than most hobbyists need.
Kelli Cases had nothing to do with Kelly tubing as far as I know.
