Gutter downpipe reducer for square guttering

This is a gutter reducer for square guttering downpipe it can reduce from the standard size enabling it to fit in between your house roof and guttering. I used ABS when making this so it is more resistant to weathering however I'm sure it will work with PLA too or PETG. It has been made to work with square downpipes around 65mm x 65mm and it reduces to around 50%. It will print without supports but for a better finish on the inside of the part, i would recommend using them. I have uploaded both the STL and the F3D incase any changes need to be made.
