Hopefully you guys will know what fan-created ship I'm thinking of. It was somewhat triangular in shape though I'm not sure how sharp that shape was. The interesting thing is that there was a "neck" like part coming from the primary hall and connected the a relatively small primary haul, which was a cylinder structure with the deflector in front and going back until it met a higher part of the primary haul. It reminded me a bit of a Star Destroyer. The "neck" was like that of a Constitution classes except on the top of the primary all, more towards the front and it was slanted in the opposite direction.
