12 to 14 mm nut trap test print by .2 mm steps

Same as my others but larger to cover 12mm 12.2mm, 12.4mm, 12.6mm, 12.8mm, 13mm, 13.2mm, 13.4mm, 13.6mm, 13.8mm, and 14mm. lets you design nut traps that will work with your printer no mater how it is calibrated. If it fits it'll work. Just try it and count to figure out what size it works with. I write the range on it with a marker so I know which test stick it is.
