modular fountain - modularer Plätscherbrunnen

This is part of a project to create a fountain for balcony or indoors.

The module consists of a circular basin with an excentric vertical column which fits into the opening of another such element. Printed in TPU this connection is stable and even more or less water tight so that it is possible to plug a hose (11mm outer diameter) from below into the combined columns and the water rises inside and finally spills over at the top.

The basin has another opening at the side where the water can flow over in a controlled manner to the next basin below, provided there's not too much water flowing and that the fountain stands upright and vertical.

There's a gap of ~27mm between the floor of one module to the water level of the basin below which dripping water will fall down and that does not make a loud sound. The idea was to create a fountain which is audible with sounds of gurgling water but in a calm and backgroundish way so you can almost forget it is there and relax.

At the basis is a modified version, the basin is larger, features 6 overflow snouts and has a 45 mm high centered wide column to help the modules above to stand vertical. the wide column has 3 outlets where a smaller hose with 6mm outer diameter can be fixed and it has not a small column to go into the base of the module above, instead the 11mm (outside) hose has to keep things together. The reason for this is that the water  hose has a T here to separate two streams of water from the outlet of the pump and reduce water flow for the fountain.

There is also a difference for the topmost module which does not need the thinner column part to stick into the next module. There is not model for this, simply pause/stop the print when it reaches that part.

All of the above relies on the water pump in a rectangular box below to both feed the water and support the fountain.
