About this 3D model

These are now deprecated and replaced by version 2 - http://www.thingiverse.com/thing:469923 This converts a different sized fan (25mm thick) for use on a 60mm x 10mm fan connector. By doing this your noise level and sound level can be EXTREMELY decreased while putting out more CFM than a 60mm can do. There are extra tall versions (30mm taller) that allow more airflow to pass.
