BambuLabs Spool Fan Bracket

This easy to print BambuLabs Filament Spool Fan bracket will permit a 40mm fan to be added to a filament dryer to increase circulation during drying process. Recommended: PETGRequired: 40x 40x 10mm DC 5V USB mini cooling fan with USB A wires (4010 cooling fan);5v source;2 (or 4) M3x12 screws;2 (or 4) flat washers (optional); and 2 (or 4) M3 nuts.Air circulation is important when dehydrating filament (e.g., PLA, ABS, PETG, Nylon, etc.), because it helps to evenly and efficiently remove moisture from the filament and decreases drying times. Here's why air circulation plays a key role:helps to ensure that the filament is exposed to a consistent flow of dry air.Moisture in filament is typically in the form of water vapor trapped inside the polymer. Air circulation helps to increase the rate of evaporation by moving the water vapor away from the filament, allowing more moisture to be drawn out.Good airflow helps to maintain a low-humidity environment around the filament, preventing the
