Abstract
A method of manufacturing a hearing device housing including at least one opening. The method includes the steps of: designing a pre-model of the hearing device housing by 3D-modelling software, the pre-model including a protective structure covering the opening, the protective structure being prepared for removal; producing a preform of the hearing device housing based on the pre-model; and removing the protective structure thus providing the hearing device housing with the opening.
