Ormerod Extruder fan Cone.

thingiverse

As any long term relationship progresses, changes naturally arise, so I've started tweaking things myself lately. Specifically, I added a simple cone to improve functionality from the 12v fan on my Ormerod extruder setup. This cone snugly fits onto the fan, optimizing airflow and helping minimize warping effects. However, there's a crucial catch - it must be removed prior to homing procedures or else it may get stuck, compromising your printer's operation.
