I designed/3D Printed a Hinge Flange ( https://www.prusaprinters.org/prints/56196-makerpipe-hinge-flange-for-emt-pipe ) that you can connect to Makerpipe connectors or a standard EMT connector ( https://amzn.to/2LOWFG8 ). It has almost a 180 degree movement. There are four holes to screw it to a wall / floor or some other project part.
