Ryobi Router Vacuum Attachment

This is an attachment that can be affixed to a [Ryobi fixed base router, model number R1631K](http://www.homedepot.com/p/Ryobi-8-5-Amp-1-1-2-Peak-HP-Router-R1631K/206757945) using screws and washers. I have hooked this up to my Rigid shop vacuum, and it seems to work very nicely.
