CR-10 fan guard

thingiverse

After finding wisps of filament wound around my CR-10's hot end fan leading to heat creep, I decided to design a simple fan guard that would snap on to the existing fan shroud and provide additional protection from filament wisps without interfering too much with airflow. So far this works well but I reserve the right to modify the design if it causes heat creep on longer prints. Should fit Ender 3 and other Creality printers that use the same hot end.
