Design matters (6): Bosch hand-blender attachment

The mini food-processor attachment of a Bosch hand-blender, upside down, with blade.

These two things:

1) The two holes in the base of the attachment to allow water to drain.
2) The rubber skirt around the edge to stop it slipping during use.

You’d miss them if they went away.
