This is the design of a 3D printable watermill with a water pump that pours water on the wheel and makes it rotate.

The total size is ~ 241mm / 217mm / 200mm (width/length/height).

For the pond I used a tray I bought with a size of 180mm / 140mm / 52mm, but I included the stl file if you prefer to print it. It is recommended to print the pond and the water canal with 100% infill and to apply some special varnish to avoid water leakage.

Other parts I bought:

• Silicone Rubber Hose 8x10mm (https://www.aliexpress.com/item/4001283598865.html)
• Water Pump, minimum power is enough (https://www.aliexpress.com/item/4001131344708.html)

The model is designed to be screwed (2.5mm diameter) or stuck to a base (not included in the model). I used a 250*260mm wood plank and some moss to decorate it.

Standard printing parameters:

• Layer height: 0.24
• Infill: 15%
• Wall thickness: 1mm
• Supports: 65º when needed
