Fantastic Halloween print... this ghost is hollow and has thin walls. The designed in support should snap away very easily (with a Replicator 2). The design size is perfect for a finger puppet or decoration... or scale up to suit (not down or the designed in support will be harder to remove).
Print in white for a classic ghost look, natural PLA for a semi transparent ghost or glow in the dark for the ultimate 3D printed ghost experience.
On a Replicator 2 use Raft and 4 shells with 35% infill. This makes the thin walls solid. Do not use support as the required support is designed-in and can be easily (but carefully) snapped away to produce a wafer thin almost weightless ghost decoration or toy... very cool particularly in glow in the dark PLA.
