USB port “switch”

This 3D-printed USB port “switch” is a compact accessory designed to easily enable or disable power to a USB connection without unplugging the cable. It fits neatly between the USB port and the cable, acting as a simple physical on/off block to control charging or power flow. With a snug fit and clear positioning, it helps reduce wear on USB ports, prevents unwanted charging, and adds convenience when using power banks, adapters, or USB-powered devices.
