This is a reupload of a dry box from thingiverse, full credit is given to them. Will be adding images when i am done printing them. Full original description is below:

Cereal filament dry box evolution based on many designs with the following modifications :

• simple to print: no support, fast enough.
• use a standard plastic cereal box and roller bearings
• include silicate box
• robust design
• gears are placed near the middle of the axis then low roll diameter is simpler
• Only 1 hole in the box to manage filament exit.
• Fit with narrow and wide spools (I enlarged cereal box a little for 1kg spools)

Notes:

For each cereal box,
you need to print

• 1 Gear support
• 2 Gears axis
• 4 wheels

You need to complete with :

• 1 cereal box (24,6 x 23,9 x 9,9 cm) example https://www.amazon.fr/dp/B07NY589Z6/ref=cm_sw_em_r_mt_dp_bCbQFbF1AN8AW?_encoding=UTF8&psc=1
• 4 roller gears
• PTFE tube
• 1 Pneufit connector
• Silicagel

Cereal boxes don't fit with wide spools. To enlarge the narrow part of my cereal box I used a heat gun and an empty bottle of Champagne :)
