Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5022483.

Remix of the Satsana duct and Ender 3 Direct Drive, uses all stock parts (fans and hotend). Should work with the stock extruder, I have the mk8 aluminum. Made for use with linear rails (mine has the linear rail mounted above the x gantry.) I've included the cura project file. (there are parts that needed support blockers to prevent inaccessible areas from getting supports).

Remixed using tinkercad.
