Manufacturing / Operating Instructions

For CNC Wood Carving:Import the STL file into ArtCAM, Aspire, VCarve, Carveco, Fusion 360, or any compatible CAM software.Scale the model according to your required mirror or frame dimensions.Check the model thickness, relief depth, Greek key details, stepped edges, and inner opening before creating the toolpath.

Start with a roughing toolpath to remove the main excess material.Then use a finishing toolpath to reveal the geometric pattern, clean borders, stepped corners, and sharp decorative relief.

Recommended CNC Bits:Roughing: 6 mm or 8 mm end millFinishing: 2 mm or 3 mm ball nose bitSharp line details: V-bit or 1 mm ball nose bit if needed

Recommended materials include MDF, beech wood, oak, walnut, pine, hardwood, or similar carving materials.Always preview the toolpath simulation before machining.A test cut on a sample piece is recommended before final production.

For 3D Printing:Import the STL file into your slicer software.Scale the model to your preferred size.For large-size frames, it is recommended to split the model into multiple printable parts.Choose the print orientation carefully to keep the front surface clean and preserve the geometric details.

Recommended 3D Print Settings:Layer height: 0.12 mm – 0.2 mmInfill: 15% – 25%Supports: May be required depending on orientationMaterial: PLA, PLA+, PETG, resin, or similar material

After printing, the model can be sanded, primed, painted, stained, or finished with wood, gold, bronze, black, antique, or modern decorative effects.

Important NotesThis is a digital STL file only. No physical product will be shipped.The model can be resized according to your project needs.Final carving or printing quality depends on your machine, software, material, tool size, and production settings.
