The Dowelmax jig ships in a nice box with all the parts embedded in hard foam. But the foam packaging is meant to protect the parts during shipping, not to provide easy access while working with the tool. The highlight of this Printable is a storage tray that provides ready access to all the small parts. (In order to be printable on a Monoprice Cadet, the tray is designed to be smaller than the Dowelmax box.) The Printable also includes a box for the spacers, a quarter-inch spacer, and a support to help you pack all the parts back into the original shipping container.
