new ender 3 volcano duct

remixed nifty part..

also version that supports screw-in thermistor.

keep in mind this is designed for the aluminum volcano blocks and titanium heatbreaks..

working on a shorter version soon for the bimetallic and copper volcano blocks which i highly recommend.

Note: bl-touch version has creality's 2.25mm thick bl-touch mount behind fan shroud

tested and works well! ..maybe not as good as a 5015 fan duct, but great for stock fan
