I started printing the legs, and that was not that easy as it should be. The legs are really long so I had to put them at an angle from absolute corner to opposite corner. Further I had to take into account the mounting screws from the heated bed.
Anyhow 10 attempts later I experimentally found the correct position.
Indeed the stock PCB works perfect. The only thing I do before starting a new print is cleaning the surface with a soft sanding pad slightly soaked in isopropyl alcohol.
Since I was not 100% satisfied with the thin design of the plates, I adapted the original drawings from 3 mm to 5 mm. SketchUp did do the job:
I’d recommend the NAZE32 board over the KK2.1. It’s usually pretty good straight out of the box (use cleanflight firmare) and much more up to date tech.
After some doubt, I decided to go for the KK2.1.5 because of the built-in screen and programming buttons. Tweaking on the field should be possible without laptop or external controller. Anyhow, I can easily change to controller in a later stage.
Battery tray completed and assembled with rubber damping balls:
After some unsuccessful drawings, I managed to create a protection cover (just in case of a future crash) for the KK2.1.5 controller.
Slices with Siplify3D, and printed with the following settings:
[ul]Layer height : 0,10 mm
Nozzle size : 0,25 mm
Infill : 50 %
PLA : ultimate white 1,75 mm[/ul]
During the build, I changed my mind. It is rather difficult to recognize the front and back side when the quadcopter is in the air.
For that reason I started reprinting some parts in a dark PLA.
In the meantime the white quadcopter is completely finished except the props. The black one is waiting for some missing electronic components I ordered today at Hobbyking.
