Spiral Voronoi 120mm fan grille

thingiverse

Towards the end of last year, I acquired a powerful industrial cooling fan from an old server rack that efficiently expels large volumes of air. However, due to its substantial weight and potential danger of causing injury if grabbed accidentally, this year, as a thoughtful gesture, I plan to gift it to someone deserving. The holes are evenly spaced at 105mm intervals with a diameter of 5mm.
