Replacement for broken and hard-to -use fan switch operator. Printed here in PET-G @ 0.3 layer height.
Remove the front panel and un-snap the existing operator from the slide switch. Some small filing on the case will be needed to fit the new operator as it is beefier than the original. A section of a paperclip retains the operator in position.
FreeCAD file included
(note: there are two colors of the new operator shown, clear and black)
