Final Checklist Before Printing

Run through this list before you upload:

• File opens without errors in at least one program
• Dimensions are correct (measured in millimeters)
• Mesh is watertight (no holes or non-manifold geometry)
• Walls are thick enough (minimum 1.2mm recommended)
• File size is reasonable (under 100MB preferred)
• No floating geometry or disconnected pieces inside the model
• Overhangs are addressed (either support-friendly or designed with chamfers)
• Consider Print orientation
  • Strength (layers are weakest along the Z-axis)
  • Surface quality (supports leave marks where they attach)
  • Print success (overhangs over 45° need supports)
