Long Blower Fan Duct

thingiverse

I needed a long fan duct for my delta. My hot-end is mounted fairly high which doesn't leave much room for the fan. I couldn't find anything that worked well for me so I designed my own. Pardon the appearance of the parts, I printed this in sopping wet nylon. Although ugly, it works remarkably well. If you print it, you can decide how many links you need for your particular set up. You can also make your own custom version from the On-Shape files, https://cad.onshape.com/documents/d048366c31a8780dc5d50f0f/w/acbbb8080b99b8b1bc5c9a48/e/2fdd3e67b086bacbf7427f40. In particular you can easily customize the length of the nozzle. It is designed for the typical AV-5015 blower fans. As shown, it uses 3 M3 x 25 screws and one M3 x 22. plus one more screw to attach to the effector. For added insurance, I added a cable tie as can be seen in the first photo.
