The upper cavity is enclosed by a plurality of walls and has a substantially planar floor surface. The bottom surface is substantially planar. The device further comprises a plurality of support members engaged with and extending from the bottom surface. Each of the support members comprise a conical shaped portion, a leg portion and a terminal portion. The conical shaped portion comprises first and second ends which define an overall length L1. The conical shaped member further comprises a diameter D1 along its length L1. The first end of the conical shaped portion is engaged with the bottom surface of the mounting portion. The leg portion comprises a first and second ends defining an overall length L2. The leg portion has a diameter D2. The first end of the leg portion is engaged with the second end of the conical shaped portion. The diameter D2 of the leg portion is substantially less than the diameter D1 along the length L1 of the conical shaped portion. The terminal portion comprises first and second ends defining an overall length L3. The terminal portion has a diameter D3. The first end of the terminal portion is engaged with the second end of the leg portion. The diameter D3 of the terminal portion decreases in diameter along the length L3 from the first end of the terminal portion to the second end of the terminal portion. The diameter D3 is substantially less than the diameter D2 of the leg portion.
