90º Connector for Gutter Downspout

I accidentally bought an extender for my gutter downspout that is meant to connect to a "wide" or "flat" oriented gutter downspout, but I liked the overall design of the extender (it flips up to move out of the way for mowing) so designed this connector to join them. 

NOTE: This part is asymmetrical. One side flits inside of the connector on the extension, while the other fits over the gutter. It's a very small difference, just a few mm, but it only fits together one way, so if it doesn't connect, try flipping it over.

This is the gutter extension that I used it with: https://www.menards.com/main/building-materials/gutters-accessories/gutter-accessories/amerimax-brown-dripper-flipper-downspout-extension/1584611/p-1444423556551-c-5812.htm?exp=false

Printed in PETG, but any material that holds up to water and UV should be fine.
