Summary

This remix provides a customizable scad for the original gutter & pipe filter (commonly referred to as a leaf catcher in USA) that FixMyRoof had created.

Unlike other leaf catchers found on Thingiverse, this design has the most robust legs (it's a plank instead of a thin stick). The robustness afford some flex when printing in PETG, but try not to push your luck :)

I have also added a "rim" to prevent the gutter filter/leaf catcher from falling through the downspout drain.

With the scad, you can:

Customize the diameter of the "legs" of the gutter filter/leaf catcher to fit your downspout drain diameter.
You can also specify the extra diameter and thickness of the "rim".

How to open the scad file:

You can open the scad file in OpenSCAD.
Be sure to also have the "MK6_Gutter_Filter_Final_repaired.stl" file in the same folder as the scad file. Otherwise the scad file will not be able to import all the pieces.
All the configurable parameters are at the top of the scad file. While OpenSCAD is unit-less, most slicers will treat it as millimeters.

The scad file should also support Thingiverse's "customizer" function. I havent mucked around with that much, so YMMV.

Files:

gutter_filter_modified.scad is the parameterized scad file.
MK6_Gutter_Filter_Final_repaired.stl is the repaired version of FixMyRoof's original design. The mesh was broken (not closed), and had to be repaired to interop with OpenSCAD. It was auto-repaired via Microsoft 3D Builder.
gutter_filter_modified_diameter_56mm.stl is an example STL file exported from OpenSCAD, with the legs diameter at 56mm.

Notes on printing:

Print upside down (with legs pointing up towards the sky).
With rims, you would likely want some snug/organic support to prevent the rims from drooping if the trim is more than a 2-3 mm sticking out.
