Calibration Cube - Spiral

Summary:

This is a calibration cube and the letters pass through the model. The model tests how well your printer can print: 

• Overhangs (X and Y letter quality)
• Bridging 
• Layer Quality
• Z Wobble (Top layers have lower quality than the bottom layers)
• Bed Adhesion 

It's hard to find such large quantity of tests in a single model so I would be very happy if you gave it a try. Enjoy!
