This is a simple filament drybox that holds a single spool horizontally. The only modification that need to do to a sealed container is to drill a 10mm diameter hole for installing pneumatic connector.
Assembly after print took only about 5min.

*The sealed container I used is ASVEL KBOX F-30 5.6L with internal dimension around 285*192*100mm.
Note:
- For spool holder disk, choose the one that fits your M8 bolt. If using a hexagonal head bolt, prefer using “spool holder disk for hexagonal cap M8 bolt”.
- In order to make this design fits to different sizes of container, you may modify the length of spacers.
- To accomodate different spool hole sizes, insert the tapered pin to different holes in spool holder disk.
- All 3d printed parts need no support structure if oriented properly. And all of them are hollowed out to reduce filament usage.
The reason I chose to design horizontal drybox instead of more common vertical drybox:
- Most sealed containers about the size of a spool are shallow in depth. Which only allows spool to be placed horizontally.
- Converting a container that is designed to be used horizontally into vertical, takes effort modifying the side of the container, and sometimes need drilling more holes, which may introduce more moisture leakage.
- There are many horizontal spool holders that are usable. Which means my design isn't too weird.
- Horizontal containers are stackable, whick ends up in smaller footprint. If not stacking too many of them(about 3 or 4), there isn't much difference between picking the top one and picking the bottom one.
