SF3D was a Sci Fi plastic model series which ran during the mid 1980s. The series was created by artist Kow Yokoyama with Kunitaka Imai and Hiroshi Ichimura. SF3D was introduced in the Hobby Japan Magazine as a special monthly installment of scratch built models. Nitto, a small Japanese company picked up the rights to make plastic kits of Kow's designs. The models produced were very high quality with crisp molding, fine details and they included copper rod, brass tube, spring coils, and photo-etched parts. They were one of the first multimedia kits produced. The series ended after a few years. In 1998, the series was reintroduced by Nitto and Kow under the new name Maschinen Krieger Zbv 3000. Or simply MaK.
