Yet another hex bit organizer

Yet another hex bit holder. This is customizable, and I recommend building a small one first (3x3) to test how bits fit. My printer is over extruding a bit so I had to make the clearance rather large for the bits to fit in easily.
I was getting errors in OpenSCAD when I tried to build a 20x20 array. I found I had to go to Edit->Preference, select the Advanced tab and increase "Turn off rendering at x elements" by an order of magnitude.
(just updated the file. Realized I had uploaded before I saved the last version This version is set up for a 3x3 test print, but it is easy to change to any size you want)
