Customizable CuttingBoardRack

This is a remix of two previous cutting board racks. This one is customizable:

You can make it larger or smaller and unlike simply scaling it in the slicer, you can control which parts stretch and shrink.

My wife like the extra space of the 4x board, but the extra internal vertical was getting in the way.

To reproduce the 4x board, in Customizer, set;

// length of base slat
baseUnitY = 28;

// number of slots.
repeats = 3;

set repeats to 2 for the 3x board.

I you don't care about matching a pre-existing holder, you can do what you want adjusting the dimensions.
