Flamingo, agama and scorpion: three point rules on the same carved shape and centre line. Drag a panel to turn all six together; scroll or pinch to zoom. Ball sizes come from the shape. No ball fit, sheets or shells. Back to the results.
Ball colours: grey: points from the shape (forks, tips, roots, bulges) orange: points from joint marks. Today's rule also keeps bends and thickness changes; all its balls are grey. The Skin bodies show Blender's Skin modifier on each tree.
