Silica gel container (for PLA filament coil)

To protect my PLA filament coil against moisture, I use reusable silica beads (aliexpress) but I had to find a solution to condition them effectively by taking the least possible space. hence the idea of making a box more suitable to be placed in the axis of a coil.

Tip: a good way to use a vacuum packaging (at will) is to use bags originally designed to store linens, we can store two reels of 1Kg with 40x50 format bags, the result is rather satisfactory.
