1. Print the pieces with 20% infill, without support or rafts. 2. Heat the NanoHack to 55-60°C using a hairdryer or hot water, ensuring the circular part remains intact due to its thickness preventing deformation. 3. As it softens, bring together the nose wings and adjustment wings on the lower jaw; you can glue them in place for added stability if desired. 4. Heat it up again and wear it on your face for final adjustments, taking care not to burn yourself; if any part feels too tight or doesn't fit well, insert a small piece of soft rubber into the contact areas. 5. Secure the "cover" with one or two additional filters in place; use a circular piece (single or double) from a conventional mask (nonwoven propylene) or add a round facial cotton pad for makeup - using half a pad can improve airflow. 6. Attach the elastics/straps.
