Packaging several items in one case?
Use a table or desk top as a physical reference
when measuring equipment, using the corner as your starting point
and leave 1.0" clear space between each item. Then simply measure
the "outside" dimensions of the layout, and the height of the
tallest object to establish your minimum inside case dimensions.
When completing this form, don't rely on OEM catalogue dimensions
or make "allowances", as your accuracy will be reflected in our
transit case design summary.
