Hi Steve,

Balancer will do a good job by simpifying your model adaptively,
keeping as much details as possible given your required triangle count.

STL is the standard format for 3D printing. Right now, Balancer only supports .obj.
But we will release Balancer nPro just in a couple of weeks. It will have metric-based
tolerance simplification (not only pixel-based), and support of STL format.
Balancer nPro is exactly for simplifying models for 3D printing.
