This is a derivative of thing:21358, Parametric Decorated Box. Material has been removed from all six sides leaving holes that form a hexagonal pattern - see image at the left.

An interesting fact about the Thingomatic is that plastic is saved if holes are cut in the model; there is no waste, no shavings to throw away. Netfabb Studio reports that the holed box plus lid has a volume of 16.5 cubic centimeters while the solid box plus lid has a volume of 24.5 cubic centimeters; a saving in material of about 30%. The hexagonal pattern makes the box an attractive and interesting object rather like those pad and pencil holders sold in office supply stores that are made of wire mesh.

Three stl files are included:

box_with_holes_05.stl, basic box with holes on all five sides
box_with_holes_04.stl, the box with a solid bottom and holes on four sides
lid_with_holes.stl, the lid with holes

Two scad files are included

box_with_holes.scad, the file which made the two boxes
see comments in the file
lid_with_holes.scad, the file which makes the lid

The openSCAD forms used to make the holes were constructed from three dimensional hexagons properly positioned in a larger hexagonal array. Thus the unsubtracted material forms the desired graphite like structure - see thing:13672.

The box and lid look best if constructed directly on the build surface which gives the base of the lid and box a nice shiny finish.

Allow the models to cool and carefully remove them from the build surface.

The decorative lids described in thing:21358 will fit the box.
