A printed filament dry box that lives on the CORE One is the whole idea behind this project, and it is a neat one. The maker printed the modification in black and orange, and it fits an enclosed printer. A compartment is built in for silica gel to keep filament dry, and there is a dedicated spot for a moisture meter as well.
Construction is straightforward 3D printing, but the tolerances show care. The maker designed the parts around 0.4mm nozzle tolerance. The cover detaches completely: a perimeter gasket seal runs around it, a central twist-lock knob holds everything together, and a circular hub sits in the middle of the cover. The lid also carries a window for a digital hygrometer display.
The demo sells it. Prusa 3D unlocks the cover, lifts it off, then reattaches the lid and secures it with the latch, and the whole routine looks clean and quick. As for a verdict, the modification earns 11 out of 10 gummy bears, which is about as glowing as any rating gets.
One trade-off stands out. The maker worked up a 2kg version, then thought it would not handle the weight or close properly. Bigger capacity looks like the unfinished chapter of this design for now, and it will be interesting to see whether that larger version ever gets another try.
