// set to 0.3 mm and your width_over_thickness is set to 2.2, the resulting
// width will be 0.66 mm.

// Thickness of the boards that make the box frame.

// in y-axis-corner it governs the height of the corners by adjusting the
// distance between ground and M10 threaded rod. (both box and single plate)

// For box model, the parts that hold Z smooth rod have one hole from front
// and one from side, and this setting makes sure that the screw from side
// is in the center of the plank.

// or 20 if you want to use the Y lm8uu holders 
// (extras/bearing-holder-single-plate-y)
