About this 3D model
This is an adapter for use a 80mm fan for the ramps 1.4 case . I use this diameter of fan because are **very silent**, around 10db You can download a M3 or M4 version with holes for use with M3x30mm or M4x30mm bolts. Using this as lid so you don't need screw at case. ** *also i include the solidworks 2014 file.*
