Anycubic ACE Pro – Upper Vent Gate Mod

This model is an upper vent gate designed to improve humidity management during filament drying. When drying filament, heated air inside the dryer gradually accumulates moisture. A controlled top vent allows the warm, humid air to escape, helping to release trapped humidity more effectively than a fully sealed enclosure. ⚠️ IMPORTANT – PERMANENT MODIFICATION This is a permanent modification. Installation requires cutting the dryer lid (for example using a Dremel or similar rotary tool). Once the cut is made, the dryer cannot be restored to its original condition.
