Universal large desiccant box

I needed a desiccant box for the safe, so that it could hold as much desiccant as possible in a compact size.I created a box measuring 125 x 190 x 30 mm (the size of a VHS video cassette cover.The contents are about 500g of silica gel, but it is also possible to place bags in it.To assemble you will need:10x sealable brass insert M310x screw M3 x 10 (possibly up to 15 mm)
