This is a dry box designed to hold up to 9 of the 250g Sunlu mini spools a lot of us buy early on.  It makes use of a bread box container you can find on Amazon and has 4 compartments for holding desiccant beads.

To install the lids, insert the non-tabbed end from the center of the model until it seats all the way.  To remove it grab the little tab, lift up and slide out.

The model is set to use supports for the connector points but a little trimming at the interface may be needed to get them to fit properly, depending on your printer.  Additionally, it is a slightly snug fit into the bottom of the box, but a light push at both ends will seat it down in.  The largest piece is 180x153x25mm so it should work for any printer.  I have tested this with both a .4 and .6 nozzle and everything fits fine with either.
