Do you want a new fountain in your room? This one is perfect!
Step 1: Components
For this project, you need only a few parts:
a small pump
some 3D printed parts
If you don't know wich flowerpot is the right, check the stl file Becken.stl. I drawed it in 3D.
You can choose every pump you want, but don't take a too big one. If you use a very strong pump, maybe the water will leave the flowerpot.
