Summary

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

The idea is to 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.

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 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.
