90mm 10 degrees Bend Pipe

This is a 90mm 10 degrees bend pipe coupler. The original design was named "Custom bend angle pipe union" and can be downloaded from Thingiverse. As it is an OpenSCAD file, user can change the parameters to get the desired size. However, it will require a few trial-and-error tests (which can take 9 hours to print) to get a practical bend pipe. This bend pipe coupler was tested for fitting 90mm PVC pipe well.
