Hi BF,

3000mm - Very Long Refractor for sure !!!

Given that you already have the lens cell and front mount you could consider some using 75mm, 80mm or 90mm Stormwater or SWV pipe. The only issue would be painting the inside black. Also if you have the standard focuser from the older donor scope you could also bung that in at the end of the tube, with some adapters which are plentiful and in many designs for typical SWV and stormwater pipes. You could also add a strengthening rib or two if you found it necessary by simply gluing a rib to the outside of the tube.

Good luck with your project.
