Documentation

Comprehensive toolkit for generating 3D printable STL files for woodworking jigs and fixtures using CadQuery. Optimized for Elegoo Neptune 4 Pro with engineering best practices and pre-built parametric scripts.

What’s Included

Skills

stl-generator - Complete guide for 3D printable woodworking jig design that includes:

• Pre-built scripts for common jigs (circle cutting, angle wedges, spacing blocks)
• CadQuery parametric design patterns
• Printer-specific constraints (Elegoo Neptune 4 Pro: 225×225×265mm)
• Structural integrity and printability best practices
• Hardware integration guidelines
• Reference files for design patterns and printer specifications

Slash Commands

/stl-generate - Generate custom STL files for any woodworking jig:

• Ask user for requirements and dimensions
• Use pre-built scripts when applicable
• Write custom CadQuery code for unique designs
• Export and provide download links

/stl-circle-jig - Quick generation of circle cutting jigs:

• Router jigs for perfect circles
• Ideal for lampshade rings and circular frames
• Adjustable inner/outer diameters

/stl-angle-wedge - Generate angle guide wedges:

• Compound miter cuts and angled assembly
• Any angle from 1-60 degrees
• Embossed angle labels for easy identification

/stl-spacing-block - Create precision spacing blocks:

• Single blocks or matched sets
• Embossed dimension labels
• Finger relief cutouts for easy handling

Usage Examples

Generate a Circle Cutting Jig

User: I need a jig for cutting a 300mm diameter lampshade ring with 250mm inner diameter
Claude: /stl-circle-jig
[Generates jig with specified dimensions]

Create an Angle Wedge

User: I need a 22.5 degree angle guide for octagon assembly
Claude: /stl-angle-wedge
[Generates wedge with embossed angle marking]

Generate Spacing Blocks

User: I need spacing blocks for 5mm, 10mm, and 15mm gaps
Claude: /stl-spacing-block
[Generates set of three labeled spacing blocks]

Custom Jig Design

User: I need a custom router template for mortising
Claude: /stl-generate
[Gathers requirements and writes custom CadQuery code]

Target Printer Specifications

• Printer: Elegoo Neptune 4 Pro
• Build Volume: 225mm × 225mm × 265mm
• Layer Height: 0.2mm standard
• Units: Metric (millimeters)

All designs are optimized for this printer’s capabilities and constraints.

Pre-Built Scripts

The plugin includes three production-ready Python scripts:

Location: stl-generator-toolkit/scripts/

Design Best Practices

Structural Integrity

• Wall thickness: 3-4 perimeter walls for strength
• Base thickness: Minimum 5mm for flatness
• Chamfers/fillets: 1-2mm to reduce stress concentrations
• Layer orientation: Perpendicular to primary load direction

Printability

• Overhangs: Keep under 45° to avoid supports
• Bridges: Avoid unsupported spans over 30mm
• Orientation: Largest flat surface on print bed
• Draft angles: 0.2mm for nesting parts

Woodworking Functionality

• Reference surfaces: Smooth, no text on work contact areas
• Alignment marks: Visual indicators (notches, text, contrasting surfaces)
• Finger reliefs: Easy handling for small parts
• Clamping access: 25mm+ clearance

Hardware Integration

Common hole sizes (add 0.3-0.5mm clearance):

• M3: 3.3mm hole
• M4: 4.3mm hole
• M5: 5.3mm hole
• #8 wood screw: 4.5mm hole
• 1/4"-20 bolt: 6.6mm hole

CadQuery Quick Reference

Basic structure:

import cadquery as cq

# Create base
part = cq.Workplane("XY").box(50, 30, 10)

# Add features
part = (
    part.faces(">Z")
    .workplane()
    .circle(5)
    .cutThruAll()
)

# Export
cq.exporters.export(part, "output.stl")

Essential methods:

• .box(w, d, h) - rectangular solid
• .circle(r) - circle sketch
• .extrude(height) - extrude 2D to 3D
• .cutThruAll() - cut through entire part
• .fillet(radius) - round edges
• .chamfer(distance) - bevel edges

For detailed patterns, see references/cadquery_patterns.md.
