40mm fan guard with capes

40mm fan guard with few ideas of custom capes.

Version 2 (Fusion 360) is a bit more rounded, in order to minimize the whistling. Sticks better on the fan than v1.

Version 1 (Tinkercad) design is available. Make your own capes as you wish !

The first version was removed, because it was too close to the fan (2mm, whistling). The current version has a 4mm space to the fan, letting it breathe much better.
