Any squarish blob of plastic near he appropriate dimensions I would think.  Look for some of the older kits like Vans and stuff that may have accessories in them.  Thats my only other suggestion.  Or just laminate some thick pieces of styrene and start shaping.

Like he said, most of those are items are just funny shaped cubes. Have a look at the real thing see how its made then make one. Nothing more than sheet and strip styrene in the right alignment.
