cyclone fanduct for HEVO MGN v2
thingiverse
Update for HEVO MGN v2. The cyclone stream circular fanduct setup is designed to create miniature cyclones around the 3D printer nozzle. This fanduct works perfectly and provides excellent bridging and overhang performance. I highly recommend covering the hotend block with a silicone sock to improve temperature stability. Although this fanduct does not directly target the block, secondary stream cooling caused by Bernoulli's principle can significantly affect the hotend block. Please check out the water test video at https://youtu.be/NWVMDyxSmvo, bridge test videos 1 and 2 at https://youtu.be/tTwLjyjG6dQ and https://youtu.be/0HL5bO8pvYs respectively, and slow motion smoke test at https://www.youtube.com/watch?v=GrL5vM0Z2nc.

Please do not ask for STEP format conversion, as it is not possible. If you need any modifications, use OpenSCAD or create your own design inspired by this one.
