Old Halls veranda rain gutter adapter

My father's old 30+ years veranda (Halls Silverline Conservatory 8' Mk II ?) still had the old rain adapter at the end of the gutter and it was more than worn after many many summer and winter.
I initially designed a very similar looking piece and printed it in PLA and he used it for something like 5 years ... but it was not ideal (the PLA was more than tired very fast).

Back to Tinkercad I changed the model, making some walls larger/stronger; moved the pipe adapter in order for it to be better aligned with the existing pipe and printed it in PETG as I finally now own a printer with a heated bed ^^
It's not perfect (the veranda gutter "walls" are in fact not 100% vertical) but it should do the trick !
