I wanted some small, easy, efficient, and nice looking desiccant containers to throw into my filament bags. The ones that fit into the center of spools looked appealing but that's a pretty large space, and I didn't want to use a ton of beads for each roll or leave a large container mostly empty. These fit the bill perfectly and are small enough that they don't get in the way. The lid screws on and off easily but holds firm. The canisters and lids print well without any special settings, 0.16mm layer height is recommended so the threads work well.

The smaller one will hold about 13g of orange desiccant beads, and the larger fits ~23g.

I included a funnel in the file as well in case you find it handy.
