I make a spare part for saddle bag Cube SKA104 0.9l for my friend, because he broke one. Maybe it can fit to other similar models too. If you need one - just print it. I use ZORTRAX Z-ULTRAT black - it is very strong material based on ABS. My profile is created for Bambulab ABS. Will be good with ASA too - ideal for outdoor use. Yes, it need supports. But they are easy to remove. Bottom of this part looks not perfect (because of supports), but it is not exposed surface.
