You downloaded a DXF, but it doesn't fit your 150W CO2 laser's bed size, or you are using 5mm plywood instead of 3mm. Here is how to fix it.
These use "flex" cuts in the material to create a bendable surface, allowing for rounded corners or integrated lids made from a single sheet of wood.

Whether you are making an enclosure for an Arduino, a jewelry gift for a spouse, or just organizing your screws, mastering the is the rite of passage for every laser owner.
This is the "secret sauce." Instead of gluing raw edges together, a DXF box uses interlocking tabs.
3mm (1/8 inch) is the universal standard. 6mm works but requires a more powerful laser (40W+ CO2).
In a standard DXF, inner corners are 90 degrees. When you insert a tab into a slot, the laser’s round beam leaves a tiny radius in the corner. The male tab has sharp corners, so it won't seat fully.
