A mold (550) comprises a main body (555) and a separable feature (560). One or more weakened regions (565) join the separable feature (560) to the main body (555). The one or more weakened regions (565) are breakable to enable the main body (555) to be removed from a shell independently of the separable feature (560) after the shell is formed over the mold (550).
