I use cura 3.6.0 to make g code for a CR-10s.

Is it possible to get a splitter for a pump that will distribute air evenly across balloons? Or will the most stretched (easiest to inflate) always blow up first

That might be why, in my experience Cura tends to overextrude a bit by default. Could also be differences in the printer itself I suppose, I have an original Printrbot Simple Metal.

In answer to the first bit of your question, you can get what are called Y-connectors, that split one source of air-flow into two. However, Physics (and experience) means that even if you do that, even if the airflow is even - which is impossible to do, from using one air supply or source - which balloon is thinnest, stretchiest, or weakest, will inflate first.

As such, it's unlikely you're going to get a system set-up that will evenly inflate more than one balloon at a time, at the exact same rate. Even professional balloon-decorating pumps that claim to do two balloons at the same time, can't, don't and won't inflate them identically. You'll always find one balloon will need to be inflated/deflated a little bit more than the other.
