Very cool projekt!
Im sure you have seen the 3D printed BLDC on youtube?
For a outrunner to have any real efficiency, the windings must have a core. Like you mention yourself, the design is not optimal. It would be awesome to integrate a laminated core into your design. I have tried to reach out to this company here : http://www.crazy-motor.com/pd.jsp?id=46#_pp=0_304_21_-1
Particularly the 15cm dia. nr. 86 (12slot) is interesting. I would not mind doing like 127 turns per coil. I’m not sure i can do it as well as a machine though, have not tried. That crazy-motor company has a coil winding machine…
