### Print settings

- For base and mount use any filament with ~80°C heat resistance (PETG, ABS, ASA, HIPS, PA, PP, PC, etc.) - For fan ducts use any filament with ~100°C heat resistance (ABS, ASA, PA, PP, PC, etc.) - Models are created for 0.4mm line width and any layer height. If you plan to use other values, check layer preview to find wrong pathes. - Use 3+ perimeters and 30%+ infill for max rigidity of mount - The feeder based on K3D Minifeeder v2.2 by Dmitriy Sorkin (https://k3d.tech/minifeeder/) and reinforced by me
