Unfortunately, the hardware store proved a dead end as did a major plumbing supply chain. The closest pipe I could find to 3in was 80mm (8cm) which is 4-5mm too wide.
Might have to look at sourcing a length of suitable pipe from overseas.
I know of a place that's local for me. They sell 3" acrylic tube, this is what I have for mine.

How much does this place sell tubes for and in what lengths?
