This is a dugout with a chamber for ground herb, spring loaded cigarette, and pokey tool. Fake cigarette is approx 75mm long with extra room in chamber to account for the spring. The spring needs to be glued in. The 2 color effect on the slide lid is just a filament change while printing.

These are the fake cigarettes I used and sized the dugout to.
