This is a Cigarette Rolling Machine which can be used to roll cigarettes up to 90mm.
Cut and add a "belt", i would recommend one of those plastic bottle labels which you can find on nearly every PET-bottle.But you can also use other things, be creative.The belt needs to be 90mm long and X mm wide. The wider you make the belt, the thicker your cigarettes will be. You should figure that out on your own.

You may want to look up how these rolling machines work.

I have created a longer one for longpapers and made the rolls conical, if you want to roll a conic cigarette. If you're interested look at the remixes.

The picture shows an older version. But it's nicer to see stuff before you print it, right?
