hedgehog lid 3d model

4-piece 3D printable hedgehog lid for IKEA TROFAST. Overall size: 400 × 280 × 6 mm. Four equal parts, each 200 × 140 × 6 mm. Parts must physically connect with simple round alignment pins and matching holes. After assembly, the four parts form one flat lid. Add 20–24 through-holes, 5.5 mm diameter, for 6 mm pipe cleaners; slightly tight so they do not fall through. Add a continuous underside guide rim, 8 mm wide and 5 mm deep, fitting inside the TROFAST opening (377 × 258 mm). Rounded corners and edges. Keep the hedgehog design from the reference image.
