This is a simple adapter to the Creality Filament Dry Box: https://www.creality.com/goods-detail/creality-filament-dry-box
The dry box comes out with a bad angled hole for filament, so when the printer is pulling the filament out of the box, it needs a lot of strength, because there is too much friction on the top cover hole.
So, this simple adapter has a dedicated hole for the Bowden holder with an M10 bolt.
Still, WIP, but fits perfectly. I want to add back holders and so on, to fasten the top cover, adapter and body. Model on pictures is printed with low quality with 20% infill, just as PoC.
Now you can print right out of the box and not fear tangled filament.
Also, this adapter allows you to store bigger filament spools in the box.
