The cartridge protractor can also be photocopied or downloaded from
our website and printed. After copying/printing always check the mm
measurement reference scale against a ruler which then makes sure
your protractor is accurate. Copiers and printers can sometimes slightly
distort the images they print, so if you find this to be the case make
adjustments to the copier or print scaling and reprint until the scale is
correct.
