Automatic drainpipe cleaner (no electricity)

### Automatic drainpipe cleaner

**Why?**

One rainy day I was watching water coming out from a drainpipe. And I thought there's some wasted energy. It would be really cool to somehow use that for something. I kept that in my mind nearly a year until I came up with this idea. Suddenly, everything was clear.

**What?**

Automatic drainpipe cleaner keeps you drainpipes clear. It works on the rainy weather using the potential energy of the falling water. **Note:** This is a first prototype and it doesn't work as well as I was hoping. So after seeing it in action for some time I'll determine all the issues occurred and fix them in the next version.

**Building the prototype**

Besides all the printed parts you will need:
* Screws size of M3 with variable lengths between 12mm to 30mm. **Tip:** Use nyloc nuts where ever possible.
* Self-drilling screws
