Leaf Ejector

thingiverse

The Leaf Expeller, like most items of this type, is designed to separate water from leaves and other solid matter within the guttering downspout. It is intended to be an "add-on" to the downspout without causing significant disruption. It is designed for use with oblong downspouts of 98mm x 48mm internal cross section. It may be necessary to sand the corners for a snug fit. The Leaf Expeller should easily fit into a 50mm x 98mm hole (you'll need to cut this out) in the outside face of the downspout. By not interfering with the other three faces, there should be no effect on the structural integrity of the downspout. When fitted, a small "tray" will project from the front of the downspout. There are a couple of studs on either side of the tray. These are for fitting a basket (not yet available) for when it's not desirable to just have the leaf litter expelled freely (like onto your nice clean deck for example). This may not be suitable if you: - Have a problem with large quantities of leaves - Have downspouts that are circular in cross-section If this is the case, you may need a different solution. If so, try checking out https://www.thingiverse.com/thing:1685566. As PLA is biodegradable, I recommend printing with ABS. Scaffolding support may also be desirable due to the protruding studs on the sides (although I am considering ways of addressing this to make it more 3D printer friendly). The basket is not yet available. It is on my To-Do list but low in priority so its a case of catch-as-catch-can. Addendum Apologies to those who downloaded the original file. I latterly discovered that the model wasn't sitting flat on the bed which tended to result in a failed print. R2 should now resolve this. Addendum 2 After a long break, I've returned to this design. R2.1 is exactly the same as the earlier versions but with a completely redone CAD file from a clean sheet. The only thing that I've altered is to make the side studs protrude further to ensure there was no possibility that the Expeller could fall into the downspout.
