This part is a custom-designed door hinge spacer block.
It is used to move a door further outward from the door frame by adding an offset between the hinge and the mounting surface. This allows the door to open wider or clear obstacles such as thick wall finishes, trims, cabinets, or other structural elements.

The spacer is a solid, one-piece block designed to provide high rigidity and long-term stability. Multiple mounting holes allow the spacer to be securely fixed to the door frame, while a standard metal hinge can be mounted on top of the spacer. This ensures proper load distribution and prevents unwanted movement or deformation during normal door operation.

The shape of the block is optimized to follow the hinge geometry while keeping the overall size compact. The design is suitable for both left- and right-hinged doors, depending on installation orientation. It can be manufactured using 3D printing for prototyping or light-duty use, or CNC machining for higher strength and professional installations.

This spacer block is ideal for custom door installations, renovations, and mechanical adjustments where standard hinges do not provide sufficient offset.
