About this model

This is is the upgraded and version of the "Accurate calibration/dimension test". The upgrade has following changes: - x and y are combined into one print - over and under extrusion is evaluated - the method has slightly changed but the principle is the same. This test jig is designed to analyse the dimensional accuracy of a printer using engineering methods. But don't be afraid: an excel sheet is included which performs all the math. You just have to print, measure and type in the numbers. A caliper is needed. Note that calibration is normally not needed for modern printers and calibration cubes are very coarse. Check: Why this is more accurate than other calibration/testing methods: - The edges have chamfers to eliminate effects from the first and last layers. - Corners are rounded to mi…
