This is a printable King Kong bust sculpture.

• Hollow model to keep the printing cost low
• Completely watertight mesh
• No pseudo surfaces
• Minimum wall thickness > 1.0 mm
• File size < 45 MB
• Poly-count < 1 mil
  Since the model is hollow, it needs two surfaces to hold the wall thickness. This increases the polycount but keeps the printing cost low.
  Printed with supports and Brim added in Cura.
  Layer 0.15mm
  Shell 1.2mm
  Bottom/Top 0.6mm
  Fill 0%
  Speed 50mm/s
  Definite my best print so far!
