hello,
skoda said you could tell me where you found the pieces that you stuck on the main parts, as if to add metal plates because I want to do it too but I do not know how to do
It's really simple: Print all the model parts twice, glue one of those prints onto thicker cardboard, and cut those panels out to glue them on top of the build part (made from the second print). That way you can add a lot of depth to the model. And if you want to add even more print it 3 or 4 times and add more layers.
