See how your 3mm parts will fit before you commit material. This kerf clearance test helps you dial in tab and slot tolerances so assemblies snap together cleanly.
Includes a ready-to-cut DXF file for common laser cutters. The test plate has multiple slot widths and tab sizes so you can measure and adjust for your machine.
Works well with plywood, acrylic, or thin metal for boxes, enclosures, models and other tab-and-slot projects. Ideal for prototyping and fit checks.
Download, cut, and refine your settings, then apply the results to full builds. Suitable for hobbyists and small businesses—please follow any usage terms.
