Split body of the T4 Quadcopter.
This is just an idea, there will probably be structural rigidity loss due to this simple split (i.e. no strategic reinforcing pins tying the two pieces back together). I have tried about 6 times to print the normal body out, but kept getting a shift in layers or air prints (E3D and PLA).
Maybe Brendan22 would put his genius towards making a better two piece body if demands are high enough.
