This is a silhouette model of the car.
The default stl is approximately 40cm and 2mm thick.
You can scale it as you like in your slicer, but don't scale it uniformly, otherwise the thickness will change (try to keep 2-3mm).
Add double-sided or a few small nails to hang it on a wall.

You can split the defect model into two parts to print and then reassemble them with glue or scale it even larger and print in more parts.

Ask me if you want other models!
