A rather filament-consuming insert for the Auer EG4322 eurobox. It adds ca. 10cm tray to store stuff in 2 layers. You need a printer with a print bed of at least 270mm in one axis.

Materials

You need at least:

• a bit more than 1kg of Filament (I recommend PETG)
• 14 pcs. M4x16 socket hex socket head cap screws (only 10 pcs. for the printed handle version)
• 4 pcs. M4x20 socket hex socket head cap screw (only for the printed handle)
• 12 pcs. M4 nuts
• 1 pc. 12mm tube, 264mm long (not required for the printed handle version)

Printing

For the metal handle version you need to print:

• 2x Eurobox spacer
• 2x Eurobox Tray

For the fully printed version you need:

• 2x Eurobox spacer
• 2x Eurobox Tray printed handle 
• 1x Tray handle

I used PETG with 3 perimeters at 0,2mm layer height and it works flawlessly so far.

Assembly

First, assemble the spacer inside the eurobox. As the side walls are usually bending slightly inwards, you might need a bit of force to get both parts in. Screw the M4x16 in, directly into the plastic.

Then put the nuts in all of the hexagonal pockets on the tray parts. Assemble the tray around the handle and tighten all screws. For the fully printed version, use the M4x20 screws for the handle.
