Calibration Vector

I designed this as alternative to the popular calibration cube and is discussed in the 3D Printing chapter of my new book "The Makerspace Workbench" from Maker Media! Use this tool to measure your printer's XYZ accuracy and calibration by measuring the dimensions and angles of each feature. Each leg of the vector is 10mm wide and 5mm tall and features both 90 and 45 degree angles.
