Fanduct V2 (2x5015) + interchangeable jets!!

thingiverse

I wanted to experiment with getting air directly blown onto the filament in a fine, direct manner, as close as possible. This design builds upon the previous one at [https://www.thingiverse.com/thing:2919312]. It will likely require further tweaks but should still work effectively - it does for me. The most notable change is that the brackets provide more alignment range and now have interchangeable jets! There are optional LEDs (3mm) available to add a touch of flair. They can be used to illuminate or wired into the fans to indicate when they turn on, just remember to add a resistor! It might be tricky to install them, but it's doable (I'll need to design a solution for this at some point). Refer to the pictures for guidance. The jets are interchangeable and can be flipped or mixed and matched. Some of them have a piece of PTFE tube inserted. Each jet has an extended version (+), as my Nozzle is offset (only using 1 out of the 2 Dual hotends). There's also a basic shape available, allowing you to design your own! The Jets require M2 bolts - if you'd prefer an M3 version, let me know. Otherwise, you might need to order bolts if you don't already have them. Here are the options: A - PTFE intended (this is my main choice). B - PTFE intended with a slight offset. C - 3-way option. D - Angled jet. E - Another angle. F - Slot with more focus in the center. You can test the air flow by lifting the Z height, going to control, and turning on the fans without running a print or heating up the hotend. As long as the nozzle temperature isn't too high, there's no issue with PTFE pressing against the heat block. You can also use the natural curve in the tube to give even more angles. If the PTFE is too tight to insert, try hammering it in or carefully using a drill to enlarge the hole. If you find that the brackets keep swinging down and hitting the heatblock, you can cable tie the top holes of the fans together - it's a bit of a hack but will stop them from drooping. With all these adjustable features, you'll likely need to adjust your slicer settings. Let me know how you get on with them and which ones you prefer!
