HEADS UP: The hatch door had a bad boolean messing up the hinge joint. Make sure to download the newest file or edit the .blend yourself before printing!

A recreation of the Metru Nui pods, designed to be more faithful to the films and comics than the toa canister lids. Attach some Technic beams to the pinhole sockets on the lower shell and the hatch door to give it an open/close function.

The shell halves fit together with M2 screws and nuts to give it a properly industrial look. If you want a uniform plastic look, you can also clip some pieces of filament and use them as rivets.
