I cut my rolls to make lift cups for my 1.75" and 2" shells.

Bit heavy duty... but OK. Re-use, repurpose etc 😄

I bet those would work good for making mines if you cut them into 1 inch sections (the one Ned Gorski shows that puts a piston between the lift and stars to achieve a higher more tight spread of stars).  I'll have to unwind the aluminum foil or cling wrap and wad it up in a drawer so I can use the tubes to try it out..... 🙂
