This is an original scad design: A leaf catcher that is triangular in shape (like a cartoon cheese slice).

This reduces the chance of your downspout being clogged with debris, and your gutter overflowing with water. Water pouring down on the side of your house is no joke! You can end up with water damage to the side of your house, or cause your foundation to settle.

The idea with this leaf catcher: have larger debris (e.g., maple leaves) land on the slope part of the leaf catcher. During dry days, it will have a chance of being blown off by wind. Smaller debris can safely fall through the smaller holes and drain away through the downspout without causing any clogs.

To prevent standing water, there are 2 optional "standing water drain holes" you can have on the side of the leaf catcher.

The scad file is customizable! You can experiment (in OpenSCAD) in various dimensions such as:

• Cheese slice height, length, width.
• Downspout ring outer diameter.
• Downspout ring position relative to the leaf catcher.
• Standing water drain hole size and location on the leaf catcher.
• Leaf catcher hole spacing and sizes.

Recommendations:

• Keep the leaf catcher width only a little bigger than the downspout hole. At least for me, my downspout hole is not "centered" on the gutter. If I made the leaf catcher width as wide as possible to fill the gutter, I run the risk of not being able to fit it.
• Print the cheese slice "standing up" to avoid overhangs.
• If you do print the cheese slice this way: position the downspout ring close to the "height wall" of the leaf catcher to minimize support material.
• Use "organic" support for the top of the downspout ring to maintain integrity and avoid droops.

• Notes:

My print settings on Prusa i3 Mk3:

• 0.3mm layer height works totally fine on a 0.4mm standard nozzle. I am sure 0.2mm layer height works too.
• Print with the "height wall" touching the base plate. The hypotenuse do not need support as long as your height wall is shorter than the "length wall" that would sit on the gutter.
• Add organic support for the downspout ring (like the attached picture above).
• 2 perimeter walls was plenty sufficient. In the scad, I used 2mm wall thickness. Feel free to experiment differently.
