Coupling for 100mm rain gutter

I was looking for this kind of model but couldn’t find one, so maybe someone else needs it too.In this coupling, on one side the gutter slides 5 cm into the fitting, while on the other side the fitting slides 5 cm into the gutter.It can be printed without supports and works best when printed with ASA or ABS.Gutter dimensions:Outer diameter: 100 mmWall thickness: 2 mmThis is my first model, so if you have any issues or ideas for improvements, I’d really appreciate your comments.
