Horizontal Expansion Ruler

thingiverse

## This is a calibration Test to set up the calibration parameters. The Ruler must be 90mm x 32mm exactly printed. And the holes are: A=20mm B=15mm C=10mm ### The process is more or less straight forward: 1. Print with Ultimaker Cura 2. Measure with a digital instrument. 3. Divide the difference by 2, and set up the horizontal expansion for the external Shell (90x32mm) by possitive if if was printed smaller, or by negative, if it was printed larger. 4. Setup 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.
