Parametric small rack ("seed box", "Setzkasten") e.g. for storing
miniatures or other collectibles.

Small racks might be printed on a 3D printer, but the main use
is to have the parts cut using a lasercutter.

You can parameterize:

• thickness of material,
• inner width/height/depth of individual boxes and
• the number of boxes in horizontal and vertical direction.
• length of the keys/slots

This third version fixes all known bugs from previous version.

You need OpenSCAD to evaluate the parameters.
Adjust the sizes in the file header of seedbox.scad.
Enable (i.e. uncomment) the variant you want to use:

• all() to generate model suitable for stl export/3D-print.
• parts() to generate 2D-shapes for dxf export to lasercut.
• exploded() to see the 2D parts in an explanatory 3D-view.

I have successfully cut the thing.

The width of the cut is not compensated. When you cut wood and want to glue it together, it is perfect. But acrylic would be too loose to be stable without glue.
