Effective 40mm fan guard

thingiverse

I encountered my fourth broken 40mm fan today, which led me to realize that existing fan guards fail to prevent tools from reaching the blades. Drawing inspiration from Japanese fences, I've created a prototype that effectively blocks wind while deterring tool-related damage. Although not fully effective against all angles, this design should prevent most common tool collisions with the fan blades. Your feedback is appreciated as I continue to refine this innovation.
