Assuming there is a box you mean...out west here we can buy thin 1/4" copper tubing in spring and summer. Not frige-grade stuff but is used for water lines feeding swamp coolers. It comes in a coil, annealed, with a paper band around it. Used to be quite cheap but now as with all else it has gone way up. Still cheaper though than the regular stuff.

I tend to buy copper in a roll and take advantage of the fact that it is
close to what i want already. On the other hand, you could cut some
extremely simple supports, mount them, and use them for a guide.
