Mini smoker build modifications?

[Smokethatstuff]

Hi all, I recently had a go at building my own mini smoker from a recycled fire extinguisher. It works grand, but I'm always up for good modifications.
Anyone got any good ideas? The original build is here. May make another perhaps?

If you like the old firefighting stuff, you could make one out of an old SCBA cylinder (when they were steel). It would be a good size, shape, and have some material thickness.

That is really cool! I really enjoy seeing things made in miniature.
