Anet A8 hidden duct

These prints allowed me to install the fan on the side and out of the way, giving me a clear view of what I'm printing! They also created a mounting point for one of those affordable endoscopes so I can record my progress. My extruder fan setup is a little different because I accidentally stuck a screwdriver into the blades of the old one, causing it to explode. So I found another one lying around and modified it. I've included a fan without a mount and one with a mount that should work with a stock setup - it's designed to mount between the fan and heat sink. Be sure to support it with wire or the drawn mount, or it will sag from the extruder heat. It's also a good idea to wrap your hot end with some "Ceramic Fiber Insulation Blanket Paper Sheet" from eBay. I found a sheet for under $2 - it was leftover from insulating the heated bed (I backed it with a piece of sheet metal). Use "5mm 100ft BGA High Temperature Heat Resistant Polyimide Kapton Tape" from eBay to hold it in place for under $1, or maybe use wire. The LED lights are the cheap "Bright Warm Cool White DC 12V" I found on eBay for under $6. You can cut them down into groups of three and power them with your printer's 12v power supply - it's a killer mod to do! You'll see even better. I hope I've uploaded everything you might need. I'm also including my master drawing. Neither of the fans is my work, but everything else is. Edit: I upgraded the chain mount/limit switch to be higher, so it matched the extruder end. I had to raise the extruder side to clear the fan - so it might not look balanced if you're using a different chain mount.
