This design requires at least 2 meters of wooden dowel rods (6mm diameter), cut to whatever size suits your needs. This was designed around a Macbook Pro, but should work fine for almost any laptop. Height, length, and width are entirely dependent on how you cut your wooden dowel rods. For additional sturdiness there are screw holes for 3M screws to keep the wooden dowels from slipping, but if printed tight enough, it should fit snuggly even without the screws.
