Don't ask me why I lost some spare time designing this.
Just feel free to use or not use it :)
Box volume is about 580ml, exactly to fit 500g of Silica Gel
There are two versions: box as a single object and box apart to print it flat and glue together.
I prefer glued version: it is stronger, cleaner and looks better.
