bankgebäude 3d modell

Create a 3D-printable piggy bank as an STL file, shaped like a realistic bank building with a classical bank facade. This model is intended as a clean base for further manual editing in Fusion 360 and Blender. The building must be hollow, with a uniform wall thickness of 2.5–3 mm, suitable for storing coins. Add a rectangular coin slot on the roof. On the front facade, include a large round vault door design as a visual element. Above the vault, add raised text “Sparkasse”. Below it, add a flat blank plaque without text, intended for later customization. On the LEFT side of the building, add a tunnel boring machine visually drilling INTO the building. The drill head must clearly point into the wall, not outward. The tunnel boring machine should be a separate solid part or a clearly separable geometry, intended to be reused later as a mechanical key. The piggy bank must open from the BOTTOM using a simple removable lid or threaded cap. The locking system does not need to be m
