Wow, that's a very good idea.
If anything, I think you might be able to charge more. I think 3 free designs/month is very generous.

PS: It's a three design limit period (not per month).
How about pay as you go pricing? I'm not going to pay monthly if I only need it every now and then, but I'd happily pay $15 per design on a non-recurring basis.
