Store your things in DNA -- this is an open-topped storage container with an abstract design that models DNA. Spheres represent sugars, and lines between spheres represent base-pairs. This was originally designed for holding business cards, but can probably be used for other things as well.

The model is implemented in a parametric OpenSCAD file, so can be customised a bit.

Note: Please use the v2 file. It has right-handed DNA, a properly parametric sphere, and has polygons extended outside the sphere limits (so should be easier to print).
