This bushing is a cylindrical spacer designed with precise dimensions for quick and reliable assembly: internal diameter 4.5 mm, external diameter 15 mm, and height 10 mm. It is ideal for shafts, M3/M4 screws, or for spacing components on mechanical supports, ensuring perfect alignment and absorbing small flatness imperfections between parts. You can easily adjust its overall height by scaling the part directly in your slicer, adapting it to your specific needs without changing the model.

When printed in TPU, it becomes flexible and vibration‑damping, making it perfect for applications involving non‑perfectly flat surfaces or for reducing mechanical stresses. If ASA/ABS is chosen instead, the bushing is suitable for outdoor use, thanks to good resistance to weathering and maintained rigidity over time. A simple, precise, and versatile component for technical projects, modeling, and light mechanical engineering.
