I have uploaded a version to accommodate the stock PB fan. It should clear the LC extruder plate now. I do not have a stock fan at the moment so if anyone prints this let me know how it works.This is designed to print all one piece.I've found that I need a fan on my PEEK for ABS and the fan on the print with PLA. This is designed to swivel when needed.This fits a generic 40mm fan from Radio Shack. Unfortunately you have to modify your LC extruder mounting plate so it can swivel.I have added a top plate to clear the larger 40x10mm fan.
