This is a video showing how I get the spring for my kinetic sculpture(   • DIY 3D printed kinetic sculpture powe...  ) from cheap measuring tap(5m).
Notice that the spring can be very sharp, handle with care and wear gloves.

It is more than likely that you will need to design your own axle/holder for the spring you get. This is just an example of how I make mine.
