Fanduct 5015 for dual hotend

thingiverse

For 2x 5015 fans dual hotends. Also has an LED strip holder which also acts as a stop. I wanted something that fit my exact needs. Other designs were causing problems; they'd hit the prints, get melted, distort, melt further and the fans themselves would fall off. So this one became a priority to solve these issues. It's a split design with some benefits: - Print separately. If one gets damaged, you just need to replace that one, not both. This makes it quicker in some sense to reprint. - Each side can be angled for better applications (The LED stops it from drooping too low). Other features include: - Small footprint, fewer collisions - Optional fan bracing to secure the fan to the mount better - Additional support to help prevent warping, hopefully not adding too much weight - Elongated mounting holes to allow for adjustments You will probably need to adjust fan settings. Most likely reduce fan speed a little. You could also play with the angle the fan is pointing and see what difference it makes. However avoid blowing directly on the heatblock as it could lead to thermal runaway (nozzle getting too cold). Bits needed: - A pair of 5015 fans - 2x M4*20mm, possibly longer - Optional arms need 2x M3*12mm, plus 2x M4*20mm bolts and nuts - 5050 LED strip (optional) - 2x M3*20mm bolts to mount all of it to the X carriage To wire the LED strip: Use a sewing needle to punch holes into the contact pads. Then you can feed the wires through the back of the strip and solder. Probably a good idea to glue the cover to make sure it doesn't drop off mid print. Refer to pictures. Production notes: It's led me to consider the science of airflow, so I've tried to design the duct with channels/grooves to direct and hopefully accelerate the air out. I also tried to make it more compact so there's less distance for the air to go. I have several versions, so at some point I might rig up tests. Maybe add swappable jets. I would like to get the jets a lot closer by making it longer, but this starts to make the angle of the fan a bit awkward. Something I'll need to think about.
