3D printable quadcopter

I've designed this for the fallowing configuration:

Crius Multiwii SE 2.5 flight controller
Bluetooth adapder
Regular RC receiver
4 x A2212-930KV motors
4 x 20A SimonK ESCs
3S 11.1V 2200 mAh battery
Battery voltage indicator, which mounts in front.

Finished frame weight is <200g.
Most parts I've printed with 0.2mm layer height, 0.8mm wall and top/bottom thickness. 20% fill.

Update 1: added different style stand off, with a 4mm plywood brace.
