A1 side vent bridge cooler

Precision Bridge Cooling Duct – Enhanced Overhang & Window PerformanceThis add-on airflow duct redirects the extruder side fan into a focused, high-velocity air stream aimed precisely at freshly extruded filament. By cooling the plastic immediately after deposition, it significantly reduces sagging on bridges, window tops, ceilings, and fine architectural details.Designed for complex prints with tight tolerances, the duct improves:Bridge flatness and span stabilitySmall window and arch definitionTurret and thin-wall detail retentionPrint consistency on high-detail, hollow modelsThe internal geometry prioritizes smooth airflow and controlled entry velocity, delivering effective cooling without over-chilling the nozzle or melt zone. Ideal for ambitious architectural prints where stock cooling just isn’t quite enough.Print cleaner bridges. Sharper details. Fewer compromises. Due to recent concerns relating to the effectiveness of this model, here are some clarificationsThe cooling is prov
