This is a lightweight filament box for keeping them dry and dust free, this model is only 75 grams and only 2 hours of print time! compared to the other most popular cylindrical dry box which is 388 grams and takes 10 hours to print.

- lid should be tight and a little hard to get off but that makes it harder for moisture to get in there and ruin your filament.

- I use silica packets so I put those in the center, but I will come out with a model soon that includes a desiccant holder

-sorry no A1 mini

if you have any questions give me a comment, Happy printing :)
