This design builds on lafactoria3D's original concept with enhancements that include a tighter fit, streamlined printing process, and enhanced airflow. Print this model using PLA filament, specifying 40% infill density, and omitting support structures altogether. To achieve optimal results, utilize a handheld hair dryer to gently shape the edges, ensuring they face outward as desired. It's essential to adhere to CDC guidelines for filter material selection, utilizing materials recommended by the agency. Users are responsible for guaranteeing a precise fit and selecting suitable filter media, consulting the accompanying chart and guidance document for further information.
