Update: The hotend hole was a bit off center, my part has melted on the first print, I just uploaded mark 2 with an added clamping screw at the top end.

Description

This is a completely rebuilt Mendel 90 fan duct with an added hole for a 3mm LED that aims directly at the end of the extruder hotend (J-Head in my case, if your hotend is smaller or bigger the angle of the LED may not be as acurate).

My uploaded image is from a former version that printed as one part, so it may differ at some small details.
