Description
Ever find yourself needing a downspout adapter after the previous one was embrittled by UV and then you accidentally stepped on it, shattering it into many different pieces, and not wanting to leave the house? Yes! No? Well, anyways, now you have an option to print a replacement at home!
Â
This design prints in three separate parts, and connected by both pins and the designed in side clips. If you are having any issue with the side clips, you can also sand things down and / or use some CA adhesive (like most super glue)
Â
Pins are easily scalable if you are having any tolerance issues with your printer.
Â
Overlapping fillets to promote flow when combining the parts.
Â
Dimensions (when together):
Best printed in PETG for better UV and thermal protection. If there is a small gap between parts, you can use filler, clear coat, varnish, or spray paint over. I used some Granite Textured Spray on my H series splash blocks to give it more of a concrete look and feel. Suggest using some CA adhesive for the pins for longevity and rigidity.
Â
The profile is set at 8% infill to save on filament, but should be good anywhere from 5-25% if you would like. Be careful with the force of inserting the connecting pins with low infill. Pins are all walls / solid, but can likely be reduced as well.
