Case that is designed for american spirits but fits most cigarette boxs. I made it so I would stop crushing my smokes during work. Snaps together with round cutouts on the hinge; it takes a fair amount of force but snaps togethr rather snuggly. As far as print sttings go im using a flashforge creator pro with a .4 mm nozzle so for my print three to four walls makes a solid print. I like to use a raft but of course thats up to personal preference.
