An external filament holder with dry sealing, modified from a model by Ryan.Fransen, thanks to his creation! The tray and material settings are already in the model file, and you can also set it to your material and color. A Y-splitter is built into the model. If you are not familiar with the printer configuration, please do not change the model file settings, just print it.

To get it done, you'll need an Ams Lite rotary shaft, as well as a PU4-4 straight pneumatic fitting and four PC4-M8pneumatic fitting. They are connected together with 4mm Teflon tubes, and several packets of desiccant can be placed inside the filament holder, and the drying effect is average, but it is better than nothing.
