About this 3D model
6x2mm magnets are tested, the others are not! This is made for the HEPA filter only, not the active carbon one, the filter can be pressed into the frame. There doesn't seem to be a need for an additional cover to keep the filter in place. Print I printed it WITH brims to prevent the corners from peeling up.
