Modular Origami-Inspired Geometric Seed Tetrahedron

Begin by milling high-grade cedar or mahogany into precise triangular segments using a compound miter saw to achieve the perfect geometric pitch. Ensure all angles are cut to exactly 70.5 degrees to allow the panels to meet perfectly at the apex.

Assemble the panels using spline joints for maximum durability against outdoor elements and seasonal expansion. Apply a food-safe, water-repellent finish to the exterior while keeping the interior surfaces raw for a natural seed-holding environment.

Integrate a hidden magnetic latch system into one of the top triangular panels, allowing the section to swing open for quick and easy cleaning. This mechanism ensures the enclosure remains securely sealed against rain and pests while maintaining a seamless visual appearance.

Finish the design by installing a laser-cut stainless steel mesh base for drainage and attaching a tensioned cable system at the peak for gravity-defying suspension. The final result is a modern art centerpiece that attracts birds while resisting the elements with architectural precision.
