A parametric box for electronics projects using perforated circuit boards. The
board is held above the bottom of the box by four corner supports, and snaps
into place to hold it snugly while allowing easy removal.
Shapes provided as children will be used as cutouts, translated to the origin
point of the top of the circuit board. Modules are provided for cutting out
two-dimensional shapes from each wall face as well as the lid.
