Now, all gutters are mounted on the wall and the main drain pipe is connected. Because this is a thick tube that is normally used for underground water pipeline, it needs support construction so the water flows in right direction. Each gutter is leveled with a slope of 1cm per 1m.
The drain tube are connected by printed parts and by silicone glue.
This is the first prototype of pipeline support.
