Great design! Direct drive really improves the Ender-3's reliability and this print works great.
I added some brass M3 thread inserts on the points in the mount attaching the E3d-V6. This helped make the mount to the E3d very rigid. Routing the cables around the front of the printer is recommended as it both cleans up the wiring and keeps wiring from tangling when printing at high layer heights. I printed the X axis cover that had points to connect a cable chain cover to cleanly route the wires.
