This Gridfinity-compatible bin holds the contents of an E3D Nozzle Fun Pack or Nozzle Pro Pack: there are seven holes for nozzles and a slot for the wrench.  The packs only come with six nozzles, so there's room for a bonus nozzle.

The bin is 2x1x2 Gridfinity units in size: 84mm long, 42mm wide, and 28mm tall plus a 3mm lip.  There are recesses in the base for magnet or screw mounting.  It is stackable.

This was modeled in Fusion360.  I've included STL, F3D, and STEP files.

Whatever you like.  If you like the two-tone look, do a color change around 27-28mm.
