About this 3D model

This is a standard 120mm fan with two blade designs one for high pressure and one for high flow. The motor is the 24mm dc motors you will find in CD-Rom spindles. You need to print with support, also 0.2mm layer height for the blade. 20% infill is fine.I have initially shared this in Thingiverse https://www.thingiverse.com/thing:2772807 I am sharing the design also here. ;)
