Oversized Nut and Bolt

UNC 1¾-4 Threaded Nut and Bolt. I printed the sample nut and bolt and I wanted to see if I could do better. I think I did. I've printed it several times, fine tuning the offsets to near perfection. I kept the layer height at .25 for speed but that means there's room for improvement. The more you play with it, the freer it'll spin. After 3 or 4 tries it'll spin like metal.
