cyclone fanduct for HEVO MGN v2
Description
Update for <a href="https://www.thingiverse.com/thing:4186819">HEVO MGN v2</a>. It is cyclone stream circular fanduct for this setup. Fanduct stream is not pointed to 3D printer nozzle directly, but it create miniature cyclone around it. It works perfectly and provide perfect bridging and overhang performance! I must recommend to cover hotend block by <a href="https://s.click.aliexpress.com/e/_dYwSpxj">silicone sock</a> to improve temperature stability. This fanduct is not directed to block, but secondary stream caused by <a href="https://en.wikipedia.org/wiki/Bernoulli%27s_principle">Bernoulli's principle</a> cooling hotend block.

Please don't ask me for STEP format, conversion is not possible. If you need any modification, please use OpenSCAD, use STL or create your own design inspired by my.
