LYP Studios got a lot of attention last month for their amazing Morningstar model, but that wasn't actually the first ship in their collection. Their archives also include a slick Centurion design that can be 3D printed and assembled at home. The applicable files are available here. If you put one together, be sure to send us pics!
I missed this originally, but LYP's Morningstar even glows in the dark! Check out the photoluminescent decals! Super cool!
