The desiccant spool dryer (Narrow version fof smaler bids) work so good when the role is placed in a hermetic bag (ziplock), th meeter always show from 10% to 15% humidity. When it reaches 15%, it's time to microwave de desiccant so it will improve it's work. You can unscrew the container from the role, without opening the desiccant trap, if you want to set it in a pole like behind the Carbon X1. The vices are solid and the kit fit on almost all company of filament. I use support type: normal(manual) and select the part that is standing behind the meter, no need for other support.
