The World’s First Open Source Gutter Leaf Eliminator

  • 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:

  1. Make the gutter wider, towards the 8” width,
  2. 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.
  3. 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
