The only thing I can think of is either put the string directly on the motors shafts (I'm guessing its going to slip a lot), or find a place to machine a pulley or buy/order some.
I found one site that sells machined pulleys, 7.95usd a piece..add shipping (its christmas) mmm might take a while..
You could try find someone locally or elsewhere that will print you some pulleys.
