Filament Shrinkage Calculator

For OrcaSlicer & BambuSlicer (using Calibration Cross)

Instructions

  1. Load the calibration model: Multi-Measurement-Calibration-Cross.stl.
  2. Print the model with 100% shrinkage and 0mm XY Compensation.
  3. Let the print cool completely, then measure it carefully with calipers.
  4. Enter your 8 measured values below and click "Calculate".
1. Outer Dimensions (for Shrinkage)

Designed values are 80mm (A, B) and 20mm (C, D).
