The new TV stand in my bedroom has a design flaw so the TV can slide sideways on the rail. The two printed parts prevent this and also keep it perfectly in the center. Simple cable ties hold it in place.
Edit in FreeCAD or scale along X-axis to fit your TV mount.
Printed in recycled Prusament PETG, 0.3 mm layer height.
