Fan Blade Replacement

It`s an replacement for crashed fan blades like mine. It fit`s the most fans with 6 mm (folder with upgraded versions for 8 mm or 5/16") shaft. The outer diameter is 230 mm. The design dosent recommend any support. My fan is quieter and it feels more powerful. UPGRADEI added an folder with multiple Versions for:→ increased pitch (unprinted, should bring more air, dont know the printability without support)→ 5/16" or 8mm shaft diameter→ changed spinnig direction (now clockwise)
