Cut files that import at the size you drew.
EngraveKit is a bench of free tools for desktop laser owners who cut boxes, engrave photos, and sell personalized work. SVG and DXF leave in real millimeters. The files never get uploaded.
Ten tools, one bench
Each one has its own page, a how-to, and an FAQ. Start with the kerf test if the joints on your last box were sloppy.
