Fitting for Gardena 4000/2 Pump

This is a replacement for the fitting between the main pipe and the tap on a Gardena 4000/2 pump. It is mostly a thread adapter, the external thread (tap side) being G1, while the internal one (pump side) seems to be more exotic (hence the need for this part).

This adapter reuses the seal from the original adapter.

Note that if you want to modify the design, to compile the scad file, you will need the thread library that is available here: http://dkprojects.net/openscad-threads/
