A zen garden tray with a water fountain surrounding it. Pipes are built into the base of the model (and up the tower).

Connect a pump ( like https://www.amazon.com/gp/product/B09XH1GYYQ/ ) to the back of the model to make the water move. Internal piping is 5mm in diameter.

You will probably need to drill out the tray holes some to accommodate for your pump's flow.

Main STL fills up a full MK3S+ bed.
