Self cleaning Leaf filter / Rain water catcher for downspout gutter, that use Coanda effect
Original design by NeedItMakeIt.
I redo it with print in one part (to get rid of the plexiglass and simplify joint and assembly),
Spiral angle is less aggressive to have cleaner print quality for the spiral, it should have the side effect of catching less junk with the trade off of less rain catch (in theory but the filter is long enough anyway).
It still catch dirt or small particles (see other NeedItMakeIt video to that problem).
Design to fit top and bottom 80mm pipe male, and 40mm female for the rain catcher. Top hole is little too wide (81mm and bottom 80,5mm). I any case i advise to adjust everything for your installation.
Support only needed for the rain collector extension part.
Printed in ASA with enough parameter to fill the spiral branch.
