What is svg2stencil?

svg2stencil is a browser-based tool that converts SVG files from KiCad's solder paste layer into ready-to-print STL files for 3D-printed PCB stencils. Drop in your exported SVG, tweak dimensions like thickness (default 0.12mm) and margins, preview in a 3D viewer, and download the STL—no installs needed, just HTML and WebGL in a modern browser. It solves the hassle of custom stencils for small-batch PCB assembly, letting you print stencils at home for painting precise apertures.

Why is it gaining traction?

Zero setup stands out: drag-and-drop SVG, auto-sizing with margins, and interactive 3D preview before download beat clunky desktop apps or manual CAD modeling. Filters tiny apertures under 0.1mm automatically, producing slicer-ready STLs that need minimal repair. For devs into custom print stencils online free, like stencil letters or numbers for PCBs, it's a quick win over paid services.

Who should use this?

KiCad users prototyping PCBs in garages or small hardware teams needing affordable stencils without outsourcing. Makers printing stencils on Cricut or home 3D printers for solder paste, or tattoo printer stencil fans adapting for electronics. Skip if you're scaling to production runs.

Verdict

Grab it for one-off PCB stencils—45 stars and 1.0% credibility score reflect its niche, single-file maturity, but solid docs and no-build simplicity make it reliable for hobbyists. Test your slicer compatibility first.
