I made dry boxes for my filament. A tray in the bottom holds the desiccant. A short piece of teflon tubing goes between the box and the feeder. They also have the advantage of being beside the printer instead of the back. In the back may make the marketing types happy because it looks nice but it is near impossible to monitor the filament. I also added a cover (and a door) to my printers. They completely eliminate warping and cracking problems printing ABS. I haven't tried polycarbonate or nylon yet. The boxes barely fit for printing on my UM2 haven't tried on my UM3 (the print area is a little smaller due to the second nozzle). I'll try to get them uploaded soon. I agree that a real filament system should be designed in. It would be way more useful then the material recognition chips.
