Non-planar hero ME part cooling fan w/ flex hose

This fan duct lets you get parts cooling going with an Ender 3 setup for non-planar printing, just like Teaching Tech shows in their YouTube tutorial https://www.youtube.com/watch?v=gmePlcU0TRw https://imgur.com/a/oPbYXSV first pic is in proportion I made this mount to be compatible with the Hero ME. It uses the BL Touch screw lock mount since you can't use a bed level sensor for non-planar printing anyway. This means you can easily switch between regular Hero ME ducts and this air hose for non-planar if desired. This mount is also compatible with direct drive systems, as shown in the pictures. My ultimate goal is to be able to print non-planar flexibles reliably on an Ender 3. https://www.thingiverse.com/thing:9457 is the flexible hose used in this print; I found two segments and one nozzle to get the air where it needed to go sufficiently. The screw holes are slightly over 2.5mm. https://www.thingiverse.com/thing:3589452 is the compatible direct drive mount I use to print flexibles. This mount works with the Hero Me with zero interference, as well as my mount. All I did was drill into the extruder arm plate on the gear side of the filament feed path and insert a piece of Bowden with the tip snipped to a point so it rests quite close to the gear and idler. This keeps the filament from getting squirted out between the gear and idler before reaching your hotend or Bowden, or whatever you use. I haven't had any issues with flexibles since doing this.
