Stock CR-10/Ender5/Ender3 fan duct

thingiverse

I just added a slanted part to the fan duct to direct the air more like the stock one. I've now tried the petsfang, hero me gen3, the bulldog, and several other different fan ducts and fan arrangements on my printers. I got good results from the petsfang on one of my printers but the other ones I got very poor results worse than stock. This model is so that I can mount the same kind of fan as the stock on the other side. This gives me great cooling and is the best setup I've had so far. I've included pictures of one of my machines that has just one fan and a picture of my other machine that I have 2 fans on. I also added the file for the little spacers I used on the screws. I used an m3 x 16mm screw with a nut and just drilled holes in the stock housing to run the bolts through. The spacers are needed to access the back screw. I previously used double-sided tape but its a pain to get everything off when you need to do maintenance.
