Raised bed drainage

--------- Deutsche Anleitung weiter unten ----------An adaptable drainage system that allows to redirect the water flow from a raised bed in any direction instead of simple downwards dripping holes. The Connector should be adapted to the bottom board thickness of the raised bed, so the Pipe corner and the connecter fit tightly together and press the liner against the board to ensure a seal. The connecter was designed for a bottom board thickness of 14 mm and a hole with a diameter of 19 mm. Feel free to scale the connector up and down to fit your needs but dont forget to scale all parts evenly. I also added a conector with a elongated pipe that can be shortened using f.e. TinkerCAD until fit. The pipe of the connector should be about 7 mm + board thickness minus 1 mm. Make sure to test the fitting of the connector and pipe corner to your raised bed before printing the ramaining parts. The whole system can then be printed in a simple configuration of:1 Pipe Corner + 1 drainage connector
