3D-Printed Oil Applicator Adapter

This 3D-printed adapter is designed to thread onto regular plastic bottles, turning them into an efficient applicator for precise lubrication of mechanical components. The fine tip allows oiling in hard-to-reach areas such as locks, hinges, or small mechanisms. The adapter ensures accurate oil distribution, preventing waste and mess. Its ergonomic design and controlled-flow nozzle make it perfect for both home and industrial use.
