These 3D-printed kiwi-nui / North Island brown kiwi eggs for the Department of Conservation were fun to make. Once filled with water they came in at about 500 g each, giving them the heft and realism of the real thing.
At 129.3 × 82.9 mm, they’re massive for such a small bird to produce — one of nature’s great feats. The shells are 5 mm thick plastic, tough enough to survive a drop, and made to be handled for advocacy and education.
A simple but powerful way to show just how extraordinary kiwi really are.
