About this 3D model

Summary Inspired by the design of Fcollingwood (Thingiverse) whom I thank in passing, I have modeled and made this spacer for a Gelid fan ( http://www.ebay.co.uk/itm/2-x-Pack-of-Gelid-Solutions-Silent-6-60mm-Case-Fans-3200-RPM-16-CFM-24-dBA/121197136910?hash=item1c37e98c0e:g:vIIAAOxygPtStirm ). I have removed the brass spacers and replaced them with 4 CHC M3x45mm screws. The original fans are of very poor quality. Do not hesitate to change them for good quality. You will gain silence and cooling efficiency.
