Automatic drainpipe cleaner (no electricity)

thingiverse

I participate with this in TheDesignChallenge: https://www.thingiverse.com/groups/thedesignchallenge/ in a theme Life Hack ### 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 * Ball bearings size 10mm x 15mm x 4mm * Some rope long enough (with a diameter of 5mm) * Aluminium pipes size 10mm x 1mm x 2000mm * Some rubber from bicycle inner tube * A house with drainpipes Building it you just put all the parts together with great amount of imagination and improvisation ;) **Videos and links** See it in action: Part 1: https://www.youtube.com/watch?v=5QrFTtcoNIA Part 2: https://www.youtube.com/watch?v=9nrghywcuFY Project pages: https://donald82.kapsi.fi/Projects/00023_AutomaticDrainpipeCleaner/ https://donald82.kapsi.fi/Projects/00025_AutomaticDrainpipeCleaner/ My project history and projects in progress: https://donald82.kapsi.fi/Projects/
