About this 3D model

This is for my Printer Chamber Project, but could apply to other homemade systems. It allows 80 mm fans to be attached to aluminum T-Slots in a nicely adjustable way. (http://davidkessner.wordpress.com/2013/08/28/3-d-printer-chamber/) Solidworks files are included for download. The pictures are a little misleading-- the fan can swivel all around without hitting the T-Slots.
