XY Axis Precision Test Ruler

thingiverse

A ruler bent in a cross shape along the X and Y axis, doubled over with two distinct creases.\r\n\r\nThis versatile tool can be used to test several key aspects:\r\n - The precision of positive and negative shapes along both the X and Y axes\r\n - Whether the X and Y axes are perfectly perpendicular\r\n - Bed adhesion during printing\r\n - The scent of your filaments while they're being printed out\r\n - The noise level of your printer in operation\r\n - And, for a more personal touch, you can even use it to determine the ideal cooking time for your favorite pasta dish, specifically the "Al dente" variety.
