The World’s First Open Source Gutter Leaf Eliminator
2 of 4
Takes 11 hours to print
I’m concerned the grate will fall
Increase the grate angle - by making the slats irregular:
Thicker on bottom
Thinner on top
Top of grate remains the same
Move the hole all the way to the bottom
Move hole slightly left to allow for the steeper grate angle
The permeable area of the crate is already a less than the pipe. If i thicken the bottom of the slats it will be even worse.
I can move the hole to the bottom, but that gives only 0.175”
The requested changes need a huge redesign, and are more complicated to do. It may take the whole next week to do them. And even then, I do not think that we will have a superior model, but just a workaround for the Luzbot mini.
I would like to focus to make a model that most people can use, ( 8” print bed with 9”-9.5” print height), and make a decent model from the start.
Even the latest design restricts the maximum flow that the 3” pipe can take (calculated for a minimum pressure, since the fall is a minimal), so larger area of crate is needed
The hole will not be printed smooth and round and it will definitely leak, so you need sealant anyway.�
My suggestions are:
Make the gutter wider, towards the 8” width,
Make the crate a separate piece that snaps on the main body even without sealant, OR eliminate the crate. You do not really need a 3D printed crate. The aluminum screen can hold the leaves. Even small rocks will bounce off. But if you need that better support why not use a wire mesh below the screen? I can add a “step” that can accept a 1/16” thick piece of mesh so the screen will not be riped.
Increase the back wall height but not too much that the water will run off in a heavy rain. Keep the industry standard slope -balance between self clearing the debris and water permeability
