Base and Name Plate Variants
There are 2 variants of Base and Name plate in this, the one in my pictures are "BaseV2" and "NamePlateAssem".

The difference for each base are:

BaseV2:
My standard base design with holes pre made so that wires can go through to hold the car.

BaseV2 (NoHoles):
My standard base design but with the holes removes, so you could drill your own holes to fit any car you wanted.

The difference for each name plate are:

NamePlateAssem:
As shown in the picture, it is made for the HKS GR Supra with modelled HKS and Toyota Supra names on it.

NamePlateHKSOnly.STL:
A generic design with just the HKS branding on it.

Colours
Colours of all other items is your choice.

Assembly
The car is tied with metal wire through the display base holes, the wire will need to be slide between the wheels and the metal body.

Back plate should slide in nicely into the display base. The name plate might need some trimming to the side to fit into the box.

Others
I have not test both generic design, but they should print just fine.

Feel free to send me any feedback on how to improve the design. Suggestion on display base designs are welcomed too.
