A Sortainer is my usual topper. In it I keep a tape measure, pencils, notepads, Toolie, a couple pieces of chalk, guide rail connectors and deflector, safety glasses, spare ear plugs (in case I forgot my ear muffs), a pair of Festool clamps, dust mask, a spare pair of AA batteries (for ear muffs radio), a 6” ruler, 3” adjustable square, and a couple other odds and ends.
This makes sure I have all the essential accessories for layout, setup, and safety.
Which CT do you have?
The reason I ask is that the CT26/36/48 have the recessed ‘garage’ space, into which you can install a cleaning set holder thing. That’s handy for holding the nozzles and tubes, etc, which would open up more drawers pace.
Like the previous poster, I got a 5-drawer Tanos Sortainer, and in the other big drawer I keep 2x CT tubes and a floor cleaning head. This is specifically for when I take my Midi elsewhere. My CT26 stays in my shop and I have the accessories in the garage space.
