Basic assembly and printing notes:

• the screws thread right into the plastic (no inserts), don't over-tighten them!
• it is best if the Filter tray is printed with a durable filament, i recommend PLA-CF
• For the Filter tray, you can choose between a tight (Plate 5) and a wider (Plate 6) grid for better Airflow
• no supports are needed
