Aquarium spraybar

This is a spraybar attachment for an internal aquarium filter with an connection tube diameter of 16.5 mm. Three knee segments allow a flexible placement of the spraybar - but of course one could think of using straight segments of different lengths as well.

The design is made in OpenSCAD and can be adapted to other dimensions as well. In order to user the OpenSCAD-code for the knee you have to use at least OpenSCAD v 2018.01.06 - older versions do not support truncated toroids.
