Description

PDF

This is a redesigned fan shroud for the Prusa XL, created to improve print quality on overhangs compared to the original stock shroud. Doesn't interfere with tool light or heater block with silicone sock. 

The airflow has been optimized to provide more even and directed cooling around the nozzle area, which noticeably improves overhang performance and reduces sagging or rough surfaces when printing difficult angles. In normal printing scenarios, overall cooling remains consistent with the original design, but overhangs benefit the most.

This model is intended for users who want better results on overhangs without modifying firmware or print profiles.
