80mm fan to 3" tube

thingiverse

This is an adapter to mate a standard 80mm fan mount to a 3 inch (75mm) tube. There is a similar one here http://www.thingiverse.com/thing:16842, but it lacks the "neck" to more gently change the diameter. It probably doesn't make much difference, but I wanted to play with the FreeCAD "part sweep" feature anyway, so here is my version! :-)\nPrint Settings\nPrinter:\nJGAURORA A3\n\nRafts:\nNo\n\nSupports:\nNo\n\nResolution:\n0.2mm\n\nInfill:\nNone\n\nNotes:\nPrint solid in ABS. The walls are all 2mm so it should be strong enough.\nHow I Designed This\nFreeCAD
