Artillery shell canister

Canister shell I made for your standard 1.75" tube.
But this was designed to slide into an empty paper towel roll (PTR) or tp rolls
(My PTR fits well inside a 1.75" tube, I cant guarantee all PTRs are the same size)
I use the PTR as a sleeve around the can and then it holds the lift charge.
There is two compartments for a burst charge and one for stars or something else.
I made a fuse tube for "timing" the can, but haven't tested it yet, and it depends on what kind of fuse you want to use.
I printed most at 100% fill, but also had a couple at 10% not much of a difference only in the base..

I made v1.0x canister the same size as the ID of the tube (42.5mm)
and v1.1x just has a lip to use less paper overall.
the lids are pretty much interchangeable I believe 1.0x has a slight more clearance.
