Face filter mask

cults3d

Air filtration face mask with removable filter material. Just add two 3mm screws for fixing filter material between grid and face of mask and rubber bands to fit behind the ears. As common print materials are solid, face part is divided, so it can be printed with soft rubber-like material - tested with TPU, but will work with other flex materials, probably. Mask can be printed whole from flex, but it will be time consuming and other materials for supports are recomended. Filtration grade depends on used filtration material, from cotton, to nanopolymer fibre. Four hooks are for rubber bands to fix mask on your face...
