CR-10 fan guard

thingiverse

I decided to tackle wisps of filament winding around my CR-10's hot end fan, which was causing heat creep. To prevent this issue from recurring, I designed a simple fan guard that snaps onto the existing fan shroud without obstructing airflow too much. This modification appears to be effective so far, but I'm keeping an eye on it in case longer prints cause heat creep issues. The design should also work for Ender 3 and other Creality printers using the same hot end setup.
