Self-centering drill guide

Let me introduce my new 3D-printable tool, designed to guarantee you maximum precision when centering holes and drawing guidelines on the thickness of any panel! This tool is the ideal companion for woodworkers, hobbyists, and makers. Here's what makes it indispensable: Multi-Diameter Drill Guides: No more guessing! The design includes integrated guides for drill bits with diameters of 4, 5, 6, 8, and 10 mm, allowing you to drill safely and precisely at the center of your panel's thickness. Integrated Pencil Guide: Need to mark the center line before drilling? No problem! There's a dedicated guide to insert a pencil, enabling you to draw a precise line along the entire thickness of the material. Smooth and Precise Movement: The main body of the tool features threaded holes designed for bearing insertion. This engineering detail ensures incredibly smooth and effortless gliding while you draw your center line, guaranteeing impeccable results. Storage Box: Keep your gear organized. To achieve the best strength and durability, especially given the required precision, I highly recommend printing this tool in PETG.
