Parametric Rain Collector

I wanted to collect rain and store it with some elevation so that I can water by gravity, without needing pumps.

I should be able to store water captured by the root gutter in a deposit almost as high as the roof by using its hidrostatic pressure. That makes gravity fed watering possible, without needing pumps.

My gutter manufacturer provides a rain collector accessory but it is designed to place a bucket on the floor next the the gutter end, that method is OK, but the water later needs to be elevated to reach all parts of the garden using a pump.

I designed this collector so that I could be able to collect rain as high as possible and send it to a deposit also placed as high as possible.

You will need to cut 10cm from the pipe, to be replaced by the collector. I recommend you place as shown in the picture. 

The collector has a leaf filter, that should let them continue their way down the pipe, while stopping them from entering the hose.

The collector is parametric with variables for most important parameters including:

• Internal pipe diameter
• Whether the top and bottom pipes have same diameter or not (flared/swaged pipe connection)
• The hose connector diameter and thread pitch
• The percentage of pipe section to use for collection.
• Whether there is a “key” in the pipe. 

The provided 3MF is for my gutter, which I guess is popular in Sweden, with 87 mm internal diameters, about 90 external, and the pipes are connector by both expanding and reducing the diameters of both ends. The hose connector is standard ½" also very popular here. 

The design can be printed without supports as it includes elements to ensure printability, simply place it in the bed at shown.

You will also need to ensure that the model is water tight, by following  watertight prints knowledge article. I use 4 perimeters, 20% infill in PETG. 

See attached instructions to access the model in OnShape where you can parametrize to your own gutter setup.
