May try this idea using that pipe :) Ultimate Bridging 3D Printing vacuum duct, maybe ?? CRAZY!! Instead of blowing air to cool filament use a vacuum to draw air in and up to overcome gravity which causes the filament to sag while bridging This has not been tested. It is just an idea. A Crazy idea? One issue is that the nozzle may push the filament down.. czcams.com/video/gxTbsTDknnU/video.html
@@ceeyx1 please if you can try it out, the pressure has to be corrected at different positions I guess and some filaments may not like any cooling actions, ABS, etc. Flexible filaments may be much more difficult I think. 💪

I had similar idea to try vacuum instead blowing air
