Very Simple 40mm Fan Cone

a very simple cone design fan shroud that can be attached to most 3d printers via the clips included.. there is a box for the fan as I originally designed it for a fan from a graphics card which did not have a surround but it can be taken off by deleting the empty box module from the scad file.. I printed it on its side with the box on but without the box on would be better printed with the cone base down.. my first publish/design so please go easy on me...
