3D-printable accessories for the Best Fence saw system.

best_fence is an OpenSCAD design project that creates 3D-printable parts for working with the Best Fence woodworking measurement system.

Features:

• 3D-printable toe clamp system for securing the Best Fence to your workstation
• Modular mount design supporting 1–10 channels with configurable spacing
• Connectors for joining fence sections (butt connector) and mounting to saw horses

• OpenSCAD 2026.02.10 or newer
• Python 3 (for documentation generation, optional)
• openscad-docsgen (installed via make setup)

Open any file in parts/ or assemblies/ in OpenSCAD and press F5 to preview.

make          # Build all STL files

Edit parameters in config.scad to adjust dimensions and settings.

• config.scad - Project-wide configuration

All project settings can be adjusted in config.scad:

• Best Fence dimensions and tolerances
• Mount height and clearance
• Toe clamp geometry and sizing
• Hardware dimensions (bolt/screw)
• Rendering quality ($fn settings)

See docs/bom.md for complete bill of materials including hardware.

See docs/assembly_instructions.md for step-by-step assembly instructions.

• API Reference - Generated API documentation
• Assembly Instructions - How to assemble the parts
• Bill of Materials - Complete parts and hardware list

make setup

This creates a Python virtual environment and installs openscad-docsgen for documentation generation.

You can override variables from the command line:

# Export with custom bolt radius
./scripts/export_part.sh parts/toe_clamp_body.scad build/stl/toe_clamp_body.stl \
    "BOLT_HEAD_RADIUS=8"

# Export with lower resolution (faster)
./scripts/export_part.sh parts/toe_clamp_body.scad build/stl/toe_clamp_body_lowres.stl \
    "EXPORT_FN=16"
