120mm fan Rostock Max side panel duct

thingiverse

This is an optional side panel designed for the Rostock Max V2 base which integrates a large standard 120mm PC case fan, no thicker than 25mm. The panel opening is shorter than 120mm tall, so it mounts the fan at a diagonal angle to a duct. Although it takes up some space within the printer, this setup should provide more airflow and less noise compared to using a smaller fan. To secure the fan in place, M3 threaded heat set inserts are used along with 30mm screws which attach directly to the duct.
