Generate custom solder stencils from gerber files for your PCB projects
Python script converts aperture flashes to OpenSCAD STL models
Perfect for DIY electronics prototyping and small-batch board assembly
Works with solder paste layers — no need for expensive metal stencils

SolderSCAD is a Python script that turns your PCB solder paste gerber files into 3D-printable stencils. If you've ever built electronics projects and wished you could skip the cost and wait of ordering metal stencils, this is your answer.

The script cleverly converts gerber apertures into OpenSCAD modules, then calls them whenever that aperture is flashed in your file. It's designed for solder paste layers specifically, handling aperture flashes without the need for complex macro support. Once you've generated your STL, just print it and apply solder paste to your PCB like a pro.

Originally created in 2012, this tool laid groundwork for DIY PCB assembly before modern printer features like auto bed leveling and build plate ironing became standard. The script is open source and available on GitHub, ready for you to experiment with and adapt to today's improved 3D printing capabilities.
