3D Model Design Concept:Valentine's Rose Heart Pendant:Main Elements:A heart-shaped pendant that incorporates a rose design either within the heart or wrapping around it.The rose could be sculpted in a stylized, delicate manner to emphasize romance and elegance.Pendant loop: Include a small hole at the top of the heart where a chain or keyring can be attached, designed for wearing as jewelry or for use as a keychain.File Type:For 3D printing: STL file format (most common for 3D printing).For CNC: DXF, STEP, or IGES for easy machining.Design Style:Minimalist: For a more modern, sleek look, the design could be simple with smooth edges and subtle details.Detailed: For a more intricate and realistic look, the rose can be finely detailed, with textured petals and a curved heart shape.The pendant should not be too large; ideally, it should be wearable as a necklace or be used as a decorative accessory.

1. Base Relief Description:Relief Style:Shallow base relief is ideal for CNC, where the heart and rose design would appear to be raised above the flat background.Low relief carving: The rose petals and heart could be gently raised, creating a soft texture that makes the design stand out without full depth, which is perfect for CNC work and 3D printing.The relief depth should be shallow enough to keep it practical for jewelry or small accessory creation, while still giving the piece a three-dimensional feel.Relief Features:Heart Shape: The heart could be the main focal point with the rose either carved into the surface or entwined around it. The base relief will allow the heart’s outline and curves to be visible without excessive carving.Rose Design: The rose petals can be added as a bas-relief, where the flower appears to be carved into the pendant, giving a subtle yet detailed 3D look.Smooth Background: The background can be kept simple with minimal texture to keep the focus on the heart and rose elements.
2. CNC or 3D Print Considerations:For 3D Printing:Material: Ideal for resin printing for high detail or PLA if you’re printing larger pieces.Size: The pendant should be small enough to be wearable or used as a charm (about 2-4 cm in height or width).Print Settings: Use fine layer heights (0.1-0.2mm) for detailed areas like the rose petals. Ensure that the pendant loop is large enough for a chain or keyring to go through.For CNC:Material: Wood, acrylic, or metal would work well for a pendant design.Toolpath: Ensure that the toolpath is suitable for delicate details, especially for the rose petals. Use a shallow depth of cut to preserve the surface detail and avoid too much material removal.Finishing: For a smooth, polished look, sanding or polishing the pendant after CNC machining would give it a professional, shiny finish.
