The hobby case is defined by units, "cells" of the case.
You define depth, height and widths of the cells.
By combining dimensions with number of columns and rows slots for shelves are generated.
Slots can be populated by:
- shelves (horizontal piece of plywood that covers full width and depth of the column. You can put anything on them, but they also provide some structural integrity. It is recommended to have a least one shelve every 2-4 slots (depending on the unit height)
- rails (3 horizontal pieces that stick out of the side and back walls of the column. They can be used to allow taller things placed on shelves below, but also some sliding drawers can be put in them.
