Under spool desiccant box

I use an 80 qt Sterilite container as a dry box for my spools. I use in spool desiccant holders, but these are inconvenient when I need to make a spool change, and relatively low volume. So I created a box with screw on lid that would allow hold a decent amount of desiccant, and would fit between the rails of a spool, and under a full Bambu Lab's spool. Dimensions are 55mm x 240mm x 15mm, slits are 1.2mm. The goal was to use up “unusable” space.I am by no means a modeling expert (it has been 14 years since I last 3D modeled), and I am by no means an expert at 3D printing (I got my printer for Christmas) so there may be more efficient ways to model this, and set it on the print plate. Feel free to adjust for your needs.
