Ender 3 Mainboard Cover with 10mm fan
thingiverse
Cover designed to replace stock cover and fan on Ender 3 Maiboard housing to fit 1012 12v fan (Buck convertor stowed in mainboard housing) It was a tight fit but everything works well and the noise is dramatically reduced. This is the fan I used: https://www.amazon.co.uk/Scythe-Case-1000-Kaze-SY1012SL12L/dp/B0017K8X4M Recycled from an old cooler.
