ER11 collet fan to clean working area

thingiverse

This compact fan is engineered to be securely mounted on the ER11 collet. Its design draws inspiration from a similar model found here on Thingy, but with a key improvement - it remains in place atop the ER11 at all times and won't fall off due to its strategic placement. The fan works seamlessly with an ER11 wrench, as illustrated in the accompanying picture. To install, simply press-fit it firmly into position; if necessary, gently manipulate the inner component to ensure a snug fit. The fan's performance is impressive, generating a strong airflow that effectively keeps chips from accumulating on the work area (as evident from the attached image). Even at 10krpm, it operates flawlessly with PLA materials. When paired with my modest motor, this upgrade adds approximately 0.2W of power draw.
