I was thinking it work hardens , so if can get it right in one !
( - stiffening a little each time it's bent more - )

Copper tube does indeed work harden. You can also anneal it with a propane torch. You'd need to buy some, experiment, and then (I predict) decide to do it in plastic.

If you were lucky enough to be able to drill a hole in outside wall, or in extra joists if next room has joists running the opposite way, then you can feed ordinary straight copper lengths in easy.
Otherwise straight copper just will be about 14" max between 16" centres joists and solder connectors to use.
The 15mm copper coil is difficult but not impossible to use for a short piece. Take it slowly and with gradual slight bends. Drill the joist holes extra big also.

Why give yourself the pain of copper coil? Go plastic for this all day long. Forget what the customer thinks is best. Who came up with the customer is always right!?
