What you might run up against is that most grading companies do a bit of their own design. Usually when you have parts injection molded you pay for the mold, and the molding company stores it as part of the deal. That's if you're making a lot of parts. If you're doing a smallish run, you get to store the mold, which will often only work on one sort of machine.
So while the manufacturer of the slab probably has the mold, they'd need permission from the mold owner to run any parts from it. And a short run will be pretty expensive.
Even once you find someone making a generic slab sort of holder - and I think I recall seeing some somewhere but can't find them- you'd still have to go through them.
What plastic are you thinking of? It might be possible to do it on a 3-D printer. Results vary depending on the printer and the sort of plastic, but it might be doable.
