Indeed it is a 3d print, the base model is done by the very talented Italianmoose over on thingiverse, while I designed the prow myself, i am very proud to say

Below a picture before painting, the lance batteries were too thin for my printer, so I redid them with plastic rods. Also, the weapons are all fully magnetised so I can use the hull for a Relictor as well. (picture with as of yet unpainted armament for the Relictor)
As for the base, I had a family member who works at a metal workshop make me a couple ( I think he made like two hundred, yeesh) discs with fitting diameter and 3mm hole out of steel, into which I inserted brass rod, hammered it flat on the bottom to plug it in, and printed the radar thingy you can see on self adhesive paper (and putting self adhesive clear plastic foil over that). Then the radar thing gets glued onto the disc and presto!
I can upload the improved design (it became clear that the angles were not visible enough on the tabletop) if somebody is interested.
