Screwable Plant Drainage

A drainage for a raised planting bed.

Assembly:

Put the screw in the grid with the slashed part pointing in the grid. Screw it up unit it hits the top of the grid. Then glue both parts together, so that no water can come through the thread.

Now this part can put through a hole in the foil or plastic of the planting bed and fixed with the nut from below. Afterwards, a hose may be attached to the nozzle.
