DC jack protective cap

This 3D-printed DC jack protective cap is designed to secure and protect the power connector and its soldered wiring. The cap fits firmly over the DC barrel jack, helping to prevent strain on the wires, reduce the risk of short circuits, and protect the connection from dust and accidental contact. Its compact, custom-shaped design makes it ideal for DIY electronics projects, prototypes, and small power modules where reliability and safety are important. The printed enclosure adds mechanical support while highlighting the flexibility of 3D printing for creating practical electronic accessories.
