Spekkens' toy model [1] can handle the measurement of a spin 1/2 along the directions $x$, $y$ and $z$. Unless I am missing something, it can't handle measurement in any direction. Would there be a known extension providing such a $\psi$-epistemic model that can handle measurement in any direction?
