Legend of Zelda - Darknut Sword

If I can figure out an absolute print box for printing this full-scale, I'll slice it up and put some holes for metal rods, cause it'd be super awesome to wield this like the Darknut did in Twilight Princess.

Full-scale dimensions: 53" x 15.25" x 4" (1346.2mm x 387.35mm x 101.6mm)
