Wood: Walnut gives a rich contrast for eagles. For a layered flag look, pair a carved relief with painted stripes.
Finish: Danish oil on walnut, or paint-and-sand-back for crisp flag lines.
Bits: Rough with a 1/8" or 1/4" ball nose, then a 1/16" tapered ball nose for the feathers and fine detail.
How to Use This Heightmap
- 1. Download the heightmap. Click the download button to get the 16-bit PNG file.
- 2. Import into your CAM software. VCarve, Carveco, and Aspire all support heightmap imports. Look for "Import Bitmap", "Component from image", or "Model From Bitmap".
- 3. Scale to your stock. The heightmap scales proportionally. Set your desired width and height, and the relief depth will adjust automatically.
- 4. Generate toolpaths. Use a ball-nose bit for best results. Start with conservative settings and test on scrap first.
What's a heightmap? It's a grayscale image where brightness represents depth: white is high, black is low. Your CAM software reads this image and creates a 3D toolpath. This file is a 16-bit PNG for maximum detail.
Coiled Rattlesnake heightmap FAQ
What software opens the Coiled Rattlesnake heightmap? +
Any CAM tool that imports a bitmap or grayscale relief. Vectric VCarve and Aspire, and Carveco, all do it natively. Look for "Import Bitmap", "Component from image", or "Model from image". If you model in Fusion 360, you can bring in the relief once you convert it to a mesh or STL.
Is this an STL file? +
No, it is a 16-bit PNG heightmap, which is what most CAM tools actually want for a relief. They import it directly, and if you specifically need an STL, the same software converts a heightmap to STL in a couple of clicks.
Do I need to invert the grayscale? +
Usually not. Our heightmaps are white-is-high, the standard most software expects. If the relief imports inside-out, just toggle the invert option on import.
How big can I carve the Coiled Rattlesnake? +
It scales to any size, the proportions are about 4:5. Common cuts are 6 x 7", 9 x 11", 12 x 14.5". Depth is yours to set, most reliefs look good between 1/4" and 1/2" deep.
What bit should I use? +
For patriotic relief detail, rough with a 1/8" or 1/4" ball nose, then a 1/16" tapered ball nose for the feathers and fine detail.
Can I sell what I carve? +
