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:
New prinjob for the top plate just released, if all goes well new photos will be published tomorrow.
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.
