A remix of mvanallen's "Aperture Fan Cover" to work with the Hero Me Gen 3 dual fan system (Though might work with the others, I couldn't say)
This was designed for my non-waterproof 8mm led strip, and is set so that the light that shines down through the gap between fan duct and printhead is blocked from reflecting off the front of the duct. However there is a shadow directly under the hotend due to the heating block. However just in front of the printhead is pretty well illuminated.
I've included a version with the Aperture Science logo as well as one without. The one without is much easier to print, just as a heads up.
The slot in the side is most likely slightly too small to slide the strip into, it's mostly there in case you want to run the wires out the side. Instead there is an opening in the 'shelf' on the inside of the slot wall a few mm wide that you can just feed the strip into the shelf from.
