This Square Corner Screw Guide is designed to help you easily align and secure two wooden boards at a perfect 90° angle while driving screws. The central opening allows you to place the screw directly through the guide, ensuring precise positioning and a clear visual check that both boards are perfectly squared before tightening.

Made to hold the boards firmly from both sides, this tool makes assembling right-angle joints faster and more accurate. For best results and long-lasting durability, it is recommended to print this guide using PETG or ABS filament.

Ideal for woodworking projects where precision and stability matter!
