Horizontal Expansion Ruler

thingiverse

This is a calibration test to set up the calibration parameters. The Ruler must be exactly printed at 90mm x 32mm. And the holes are: A=20mm B=15mm C=10mm The process is straightforward: 1. Print with Ultimaker Cura. 2. Measure with a digital instrument. 3. Calculate the difference, divide it by 2, and set up the horizontal expansion for the external Shell (90x32mm) positively if it was printed smaller or negatively if it was printed larger. 4. Set up the "Hole Horizontal Expansion" using the same criteria but measuring the holes. In my case, the horizontal expansion needed was zero, and the hole horizontal expansion was 0.1mm; then the resize was corrected.
