3D Printable Concrete/resin Cup Mold Hexagonal Design

Produce striking, industrial-style geometric cups or small planters with this highly precise Stacked Hexagon Cup Mold. Engineered for perfect casting, this multi-part mold system features a split outer shell with bolting flanges and a precision drop-in inner core, ensuring consistent wall thickness and easy demolding every time.

Whether you are 3D printing this as a master for silicone mold making, pouring concrete directly into a TPU print, or CNC machining a durable production mold from aluminum, this asset provides the professional-grade CAD files you need.

Key Features:

Industrial Geometric Design: Features a bold, stacked hexagon (nut-style) outer texture that stands out in any home or office decor.

Professional Multi-Part System: Includes a two-part outer shell with integrated flange holes for bolts/clamps, and a perfectly toleranced inner core plug.

NURBS Precision: Designed in Plasticity. The included STEP file ensures flawless, mathematically perfect flat faces and chamfers for CNC machining, completely free of low-poly mesh faceting.

Versatile Application: Ideal for casting concrete, cement, plaster, jesmonite, or resin. Perfect for making pen cups, small succulent planters, or candle vessels.

Included File Formats:

STL: High-resolution mesh, ready for immediate 3D printing.

OBJ: Standard format compatible with most 3D software.

STEP / STP: Solid CAD file, perfect for CNC toolpath generation or parametric editing.

Plasticity: The original source file, allowing you to easily adjust tolerances or scale if you use Plasticity 3D.

3. Settings and Manufacturing Instructions

For FDM / Resin 3D Printing:

Print Orientation: * Outer Shells: Print standing upright, resting on their flat bottom edges.

Inner Core: Print upside down, resting on the wide top flange.

Supports: You may need minimal supports for the bolting flange holes on the outer shells. The hexagonal geometry itself is designed to print without supports if oriented correctly.

Layer Height: 0.16mm to 0.20mm. (For the smoothest release when casting, print at a finer layer height or lightly sand and seal the print).

Infill: 30% - 40% (Grid or Cubic). You need a dense infill to prevent the mold walls from bowing under the hydrostatic pressure of the poured casting material.

Walls/Perimeters: Minimum of 4 to 5 walls for maximum strength and water-tightness.

Assembly: Use standard M3 or M4 nuts and bolts through the flange holes to tightly secure the two outer halves before pouring. Apply a release agent (like silicone spray or petroleum jelly) to the inner walls before casting.

For CNC Machining:

Software: Import the .STEP file directly into your CAM software (e.g., Fusion 360, Mastercam) for exact geometry recognition.

Tooling: Use a flat end-mill for the majority of the clearing and finishing on the hexagonal faces.

Material: Aluminum is highly recommended for creating a permanent, heavy-duty production mold, or use high-density polyurethane tooling board for prototyping.
