What it does. Large patterns, a full-sheet sign, a big stencil, a pattern bigger than any single sheet of material, don't fit on one CNC bed or one piece of stock. This tool slices an oversized SVG into bed-sized panels and adds interlocking finger or puzzle-piece tabs at every seam, so the pieces line up and join cleanly once they're cut.

Why it exists. I built this for my own woodworking shop. I wanted a really big whale for the wall, far larger than my CNC bed could cut in one piece, but I still wanted it big enough to be a real showpiece. The answer was to cut it in smaller panels that each fit the bed and join with puzzle-style joints so they lock together. Doing the layout by hand, working out where the cuts fall and drawing matching joints on both sides of every seam, is finicky and easy to get wrong. This tool does that math so you can focus on the design instead of the seams.

Where it fits. Built for CNC routing and large-format templates, this is a companion to the site's 3D printing tools: same maker workshop, different machine. Everything is exported as SVG, ready to bring straight into CNC or laser cutting software.
