Silent Ender 3 PSU fan duct

Silent Ender 3 PSU fan duct

Description

Since I don't want to invest in new fans for my Ender 3, I was searching Thingiverse for a simple and silent fan duct and keep my PSU cool. I couldn't find one that fitted my expectations, so I designed one. This fan duct is made so that the air can flow easy, but the initial sound is blocked due to the wave pattern. The wave pattern makes the air flow in such a way that 'wind noise' is reduced.
