Small 3D Calibration Ruler
thingiverse
I modified RichieC's 3D Calibration Ruler in OpenSCAD to make it more compact, so you can now print it on smaller printer beds like those found on the Monoprice Select Mini. I left everything else the same - the ruler markings and hole sizes are still identical.
