The idea was to create a waterwheel, which is driven by a water pump und additional lifts water into a second circulation to feed a waterwork (plateaus).
The waterlevel must be almost under the wheel so the three buckets can fill themselves with water.
Additionally you have to use aluminum strives for the frame and a PVC hose for the pump.
In the top item i have drilled 3 whole to the back and to the sides into the aluminium and the hose, but not in the direction of the wheel so the water can smoothly leave to start element.
The wheel is fixed on a 8mm threaded rod, which is hold with 2 bearings in the frame.
I have created this thing with 123Design, you can download the complete construction in one 123Design File to adapt it at your wishes.
Here the wheel in its first real life: https://youtu.be/_AevDTsDgLg
I am happy with my Wanhao 5s mini, because it has a giant pressure bed.
But the wheel is so big, that the wheel must be printed with 2 halfes.
The prints are huge and need a lot of filaments, so think on every part, how many infill is needed at this position!
I have used all my rests of filament, you can see that at pans :-)
