// Gridfinity Baseplate
// Gridfinity is a system to help you work more efficiently. This is a system invented by Zack Freedman. There are two main components the baseplate and the bins. The components are comprised of a matrix of squares. Allowing easy stacking and expansion

@settings(defaultLengthUnit = mm)

// Number of bins in each direction
countBinWidth = 2
countBinLength = 3

// The total height of the baseplate is a summation of the vertical heights of the baseplate steps
height = firstStep + secondStep + thirdStep

// define a function which builds the profile of the baseplate bin
