Schuko Ground Ring Adapter

What this part isThis is a printable grounding ring that adds side contact grounding capability to flush-mounted two-pin European outlets (Type C or similar) that normally lack a protective earth connection.The adapter fits between the ungrounded receptacle and a Schuko plug, introducing a mechanical interface for a proper ground connection via a salvaged grounding clamp embedded directly into the print. A green-yellow wire exits the housing and can be connected to a verified earth point nearby.This part is designed for controlled laboratory or workshop environments, where users understand mains safety and wish to test or operate grounded equipment temporarily without altering fixed wiring.Crucial compatibility noteThis adapter is intended only for flush two-pin outlets—the type that sits flat against the wall or fixture surface.It will not fit into recessed outlets because the surrounding cavity leaves no clearance for the grounding ring’s body.
