8020 Dust adaptor for Festool dust extractor

This is a dust adaptor for the end of a piece of 3030, or 3060 80/20 extruded aluminum. I'm using it on my custom router fence made out of 3060 (3" x 6") 80/20 brand extruded aluminum. The holes will accept 5\16" screws. The dust port is made to accept the 34mm hose from a Festool dust extractor. I made small indentions in the tube to allow for button head screws. I made the outer edge of the base so that you will still be able to slide T-nuts into the slots on all sides of the extrusion.
