Make the cardboard case

Draw the box on the cardboard. Trim the excess parts and fold by the lines.

Paste a strengthening in the areas where the motor will be attached and use double-sided tape to close the box. If your cardboard is very hard use scotch tape to keep it closed.

Use the PDF file (available here) as a guide.
