Printing Settings: - Material of choice - 100% Infill Density - Two Wall Layers - Three Bottom and Three Top Layers - Rectilinear Infill Pattern First Part Requirements: - No Support Needed Second Part Requirements: - Side Pipes Require Bed Support This mask has been extensively modified to facilitate printing in separate parts, which can be secured together using four M3 screws. Unfortunately, the original creator of the face-fitting component remains unknown. Some minor sanding may be necessary for optimal part alignment. For maximum filtration efficiency, use any suitable fabric for dust filtering and polypropylene fabric for biological filtering. The 20mm pipes on either side can be easily adapted to accommodate various filter configurations. To assemble the filter, simply insert your preferred material between the two parts, then attach a 20mm hose if desired. For improved fitment, apply adhesive foam or silicone tape to seal any gaps.
