Hex Shank Bit Holder - Parametric

This is a remix of the hex bit holder by TBRIshtar : http://www.thingiverse.com/thing:241501 - thanks TBRIshtar! This remix mimics the original as close as possible but has the following features: Almost fully parametric; Any number of rows and columns, still keeping the edge rows open on the sides. This is nice if the hex shank has the bit size stamped on it. Footer height can be adjusted; Wall height can be adjusted; Allows easy scaling in the X and Y directions if your printer causes the hex holes to be too tight, like mine does. I use the OpenSCAD fillets lib https://github.com/jfhbrook/openscad-fillets by jhfbrook for filleting the edges - Thanks jhfbrook!”
