Micro Kossel Upgrade, Part 3

And now for the 3rd and final update on this project. After my last post, the version 3 effector warped during a 15 minute test print, so it was back to the drawing board for revisions. This time the solution was fairly simple, I just raised the bottom of the effector to be parallel with the bottom of the heat-sink and added some mounting holes for the heat-sink fan to the clamp section since the E3D duct won't fit on this version.

Assembly and installation is mostly the same as for the V3 design, only change is that only the upper mounting holes for the clamp are used, the lower ones were removed to allow space to install the 3010 mm fan properly.

Non-printed parts:
1 E3D v6 or Lite6 hot-end
2 3010 mm box fans with 2 corners removed
4 M3x20mm screws
Kapton tape

I've been printing for over 14 hours with the V4 effector and it's worked flawlessly with no failed prints so far. Overall print volume is currently 10 cm tall by 11 cm diameter, which is exactly what the Micro's original design concept envisioned.
