One of the best deals going is aluminum shower curtian rod!!!
Thin wall alum tube usualy 1" dia, very easy to cut and very stiff for weight, and cheap and at any hardware store. fits into some pvc fittings for some connections, use epoxy to "shim" loose connections. Good luck

Depending on how big the thing is pvc pipe would work pretty good, what are the dimensions and orientation of the model?

Large columns of packing foam has worked well for the roller coaster projects I had my students make. It is cheap, light, and easy to mold.
