The ground settled and opened a gap between my rain downspout and the drain pipe.  I couldn't find anything at the store that would work to fix it.  And I didn't want to dig up and reposition the drain pipe, so what to do?  Print the solution!  

Printed in PETG and it works great.  If you have a similar issue you could scale if needed or at the very least this might trigger inspiration on how to fix the issue.
