Down Spout Extension

thingiverse

Please Post a Make! With years of rain running down the house downspouts, they shrink! They're too short to reach the drainage pipe and water spills onto the ground. To the rescue – the Drainpipe Extender. I have three pictures: 1. Before repair 2. After repair before painting and gluing 3. Final result This is a two-part plastic collar that fits around the end of the pipe and makes a proper connection. The object is in two parts for easy installation. Gluing the parts together is best done with a construction adhesive that has polyurethane. This rather nasty ingredient will harden to a permanent bond, but before then it's difficult to use. I have found the easiest solution is to paint the contact surfaces with the adhesive using a small disposable brush – I think they're known as Acid Brushes (see picture). Paint the surfaces evenly with a thin layer and press them together. Unlike wood glue, clamping is only needed to hold the pieces in place; they don't need a tight approximation. Do not wipe off the excess. The adhesive will harden to a chewing gum consistency in about two hours. At this point, peel off the excess. Final hardening takes two to three days, and it's EXTREMELY hard. I printed mine with PLA since it's in the shade. I also painted it white to match the adjoining plastic connector. I have two versions: 1. 45mm extension 2. 80mm extension
