A device is disclosed that includes a first polymer body having tacky properties. The first polymer body has a substantially-flat exterior surface. One or more protrusions are disposed on the substantially-flat exterior surface of the first polymer body. When the one or more protrusions are in contact with a substantially-flat exterior surface of a second polymer body having tacky properties, the adhesive force between the one or more protrusions and the substantially-flat exterior surface is less than the force of gravity on the first polymer body.
