mQuad - a printable Blade mQX frame

I'm designing a complete new frame for the Blade mQX.
It should be working now, altough it might be complicated to print the gearbox, because it's calibrated for my printer.
Mine is now printed and working!
Please tell me in the comments if it works for you.
Changes:
strengthened arms and centerplate
added a grooved arm to reinforce with carbon fibre / kevlar / etc.
