This is the ultimate arbor cover for the Festool TS-55. I designed and printed a simple arbor cover but still thought that the dust collection could be made better, and the ultimate arbor cover was born. Simple snap on and snap off in seconds. Three contact points, so it is nice and sturdy. Can be printed on the A1 mini…….use the SPLIT design. A few drops of super glue and you are ready to go! Have fun, be safe!
