My nozzle here is a mechanical crayon, but a thin straw with a bead could work too;
Black coated wire with a bead and wire prongs finish off the vacuum for the power cord.
Finishing touches were added with a bit of paint and paper. I finished mine off with a little green and red paint for triangles to resemble on and off buttons and cut the logo from a newspaper advertisement.
The top handle and side latches are black cardstock glued on to give dimensions to the overall look.
And there you have it, a shop vac for a room for Dad or the dollhouse workroom or garage!
