Box for holding desiccant (e.g., blue silica gel). 100 mm x 50 mm x 14 mm with 1.5mm wall thickness. Has snap on lid. The size of box is close to the typical 4" x 2" x 1/2" perforated aluminium boxes often sold with drying agents. A box this size should protect about 3 cubic foot space from rust and atmospheric moisture. Used Slic3r Ver 1.1.7 and printed on a Lulzbot TAZ Included stl versions with and without corner pads (to prevent warping). Also attached openscad source files so you can change the dimensions of the box if needed.
