3D printed earplugs
Most of the simple earplugs cannot be attached to the ear for a long time. In the proposed design, the holders keep the earplugs attached to the ears, so they can be used also during sleeping or in other daily activities. Also, a valve can be used for the reduction of the pressure; it can be open or closed. Flexible materials are recommended for the main parts and PLA for the valves.
Supports or rafts
This part does not need supports or rafts.
