A little filter to fit into the top of a down pipe to stop leaves and debris getting into the down pipe.

Diameter is 56.5mm at the pipe fitting which just matched the fitting section of my down pipe. The object can be scaled to fit other pipe diameters.

The object is available on TinkerCad, search for "leaf catcher 2"

The object was derived from an SCAD item on Thingiverse, and additions made in Tinkercad to suite my particular purpose, and drain pipe.
