puzzle for 3d printing 3D print model

The puzzle was created with solidworks and exported as stl. for 3d printing. A solution can found among the attached images. The height and width of the dashboard are 1 mm bigger than the whole pieces assembled so it would be easier to put the puzzle together. The board has holes in it in order to help with getting the pieces out in case case they get stuck somehow. The puzzle can be rescaled using the appropriate applications. Hope you enjoy solving it!! :)
