Cross-shaped opening guides drill placement and clears sawdust

This 3D-printed workshop tool is a simple yet effective drilling jig for creating straight, perpendicular holes in woodworking projects. Designed for single drill-diameter use, it offers customizable specifications to fit your exact needs and board thickness.

The jig works by positioning your drill through its opening, then lowering it flat against your workpiece without shifting the drill point. The integrated cross marking helps you align properly and manage sawdust removal during drilling. Winged variants are included for use with standard 18 mm boards, allowing the jig to fold securely over your work edge.

This is a guide to assist your drilling accuracy—not a guarantee of perfect perpendicularity—but a practical tool for improving hole alignment. Perfect for carpentry, woodworking, and general workshop use. Designed parametrically in OpenSCAD for flexibility.
