Fire Starter is designed to be printed on a multi-extrusion 3D printer. There are 4 different stls here to be printed all at once. You can choose up to 4 colors for this print. I've also included an stl version for single extrusion; Full Flame.stl.
Suggested colors per stl file:
BodyFlames.stl - Red
MedFlames.stl - Orange
HighestFlame.stl - Yellow
Eyes.stl - Black
Fire Starter may also look cool in shades of blue and white!
No support is needed. Print in whatever material you like; PLA, ABS, PETG, possibly even TPU.

I designed this in SolidWorks using revolve, loft, and surface modeling features. Each stl I exported was a solid body in solidworks. Regardless of the program used to create multi-extruder models, it seems the common requirement is to make each different extruder material/color, its own solid body inside the part file, and make sure they dont fill the same space.
