Sprue Cluster Tree

Sprue Cluster Tree

The Sprue Cluster Tree replaces the trunk-and-branches idea with a cylinder built as a lattice: two families of crossing helices form diamond-shaped cells, and every crossing is an anchor node where a copy of the piece is attached through a short connector.

Where a radial tree spaces pieces along a stem, the cluster wraps them around a cage — many more pieces in the same flask, and a runner network that feeds them from several directions at once.

The lattice

• Cells Around — how many cells go around the circumference, which is also the number of helices in each family.
• Rows — how many rows of cells up the cylinder.
• Wire Diameter — thickness of the lattice tube itself.
• Move Z — shifts the lattice vertically against the base, to clear the central cylinder.
• Perimeter rings — optionally draws the top and bottom rings that tie the nodes together.

Hub and legs

• Central Diameter / Height — the cylinder that runs from the plate up to the first row of the lattice.
• Leg Diameter — thickness of the legs anchoring the structure to the plate.
• Leg Separation — spacing between consecutive legs measured along the connector.

The pieces

• Length, Angle, Rotation, Inside — the connector from the node to the piece: how far out it sits, its vertical inclination, its spin on the connector axis, and how deep it sinks into the model.
• Diameter — the extra holding connectors reaching from the node to the model.
