3D part design with OpenScad #23 unlimited pipe fitting module

This module is for making pipe fittings, you can add branches, adjust each branch angle, branch inside and outside shape, length and diameter.

Here is the code, just copy and paste it into the editor in OpenScad:

You can add branches by simply copying and pasting one of the other branches and changing the number to the next one in line.
