Shrinkage and Accuracy Calibration Object

By printing this object, you can calibrate your 3D print dimensions and also calibrate the shrinkage of each filament material.
Dimensional accuracy test: all sizes should be exactly 40, 20 or 10 mm.
First calibrate your extrusion multiplier, then print this object at scale 100% with the large square side facing down (upside down).

- Inner diameter 10mm & 20mm
- Outer diameter 40mm

Vertical:
- Total height 40mm
- Half height 20m
