Customizable stack-able box with label to hold ammunition.

NOTE: If you get an error from the Thingiverse Customizer, download and open the file in OpenSCAD at https://www.openscad.org/. This scad file creates a stackable box with round holes. I use these boxes to store ammunition that I've reloaded. You can change the hole diameter (shell diameter), overall length of the object to be stored (OAL of the finished round), label for the box, and the number of rows and columns in the box. For example, if making a box to hold twenty five 9mm Luger rounds, use these values: internalCube = 9.5; OAL = 29.75; textForBox = "9mm"; numRows = 5; numColumns = 5; Give some extra room for the round diameter and OAL of the round as filament may shrink, making extraction easier. Print one lid per stack of boxes, as the box above acts like a lid.
