------UPDATED 11/10--------
V2: Added angry eyebrow and blaster! Also an optional body file w/ hook for ornaments, keychains, etc. Happy printing!

Added full model (pre-meshixer) for reference.

Printed on a MakerBot Replicator 2, 10% infill and 2 shells.

True Purple filament for body, Neon Green for the base and front pieces, True Red for the blaster.

STL's are all in the correct orientation for printing. Body and blaster need supports. All pieces printed with raft due to size.

Once printed, superglue all pieces together (see final pic for reference) and proceed to take over the world.
