My OO scale model of an Austin Maestro turned up today. It can be printed in either FD or FUD. I've ordered the FD version first on the basis that if it works in that material, it will definitely work in FUD.
The model consists of the body, chassis, wheels, headlamps and tail lamps as separate pieces.
3D printing means the interior can include a details like the steering wheel and open headrests.
It has printed very well, though of course it will benefit from some careful sanding and painting to smooth the surface.
For the photos I have done a dry run assembly without any glue, and haven't put the lights in place to avoid any chance of losing them.
The model's page in my shop is
here. There's also various other versions, including the car in HO and N scales, with metal rather than plastic bumpers, as well as a model of the Maestro van.
