SVG2Stencil

3D print a solder paste stencil for any circuit board. Export the paste layer from KiCad as SVG and get a custom STL file you can 3D print.

Usage

1. Open index.html in a browser
2. Export your paste layer from KiCad: File > Plot > F.Paste (SVG format)
3. Drag and drop the SVG file onto the drop zone
4. Adjust stencil dimensions:
   • Width/Height: Overall stencil size (auto-sized to fit with 20mm margin)
   • Thickness: Stencil thickness (default 0.12mm)
5. Preview the stencil in the 3D viewer (drag to rotate, scroll to zoom)
6. Click Download STL to save

Requirements

• Modern browser with WebGL support
• No installation or build step required

Notes

• The tool parses filled SVG paths as apertures
• Apertures smaller than 0.1mm are filtered out
• STL files may need minor repair for 3D printing (most slicers handle this automatically)
