This is a wrench for Fiber Optic ST connectors. The panels get loaded up and it becomes a major pain to put in jumpers into the breakout panels when they are full.
Originally printed with an SLA printer on with AnyCubic resin and was strong on its own so any other material would be a VAST improvement in stiffness and ridgidity. Grips TIGHT onto the body of the connector and has enough draft angle to accept most ST connectors.
