Downspout Filter replacement filter / grate

pinshape

This is a replacement filter/grate for an InvisaFlow 4400 Flex Grate Downspout Filter purchased from Amazon.com: http://smile.amazon.com/gp/product/B0061Q5DW2/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1. Our dog destroyed the original filters, and I needed to replace them quickly. The 3D printed parts performed exceptionally well. I also designed a deflector that attaches to the inside of the upper part of the downspout, deflecting water towards the back of the filter instead of out through the opening. To assemble the replacement filter/grate: 1) Print the parts. I printed the "chevron" side facing downwards on the build plate and had the "vertical stripe" reinforcements span over the top of the chevrons. This approach worked well for me, but your results may differ. 2) Use zip ties to attach the 3D printed parts to the original downspout filter.
