Slide the right and left panel towards yourself and unlock the lid. 

Printing:

All parts printed at 0.4mm nozzel and 0.2 layer-height. Except the hinge; 0.12mm layer-height. All part are oriented the correct way to print. You'll need to use supports to print the lid in upright position. This makes it also possible to iron the top-layer. 

Assembly:

Slide in both panels into place in the body before glueing it to the bottom. Beware to only glue the body to the bottom, and not the panels.  The glue the hinge into the recess at the back of the lid, then put the lid on the body with the side-panel closed, then glue the other half of the hinge to the body.

Paint your fancy.
