With a friend, we've made a mini quad-copter with clips for assembling.
It's not necessary to glu it, just "clik" it.
I put HK multistar 1704-1900 on it and a multiwii FC, the mobius and another litle cam for FPV with video transmiter.
The weight is just a litle bit more than 500grs with a 1300 mah 3S.
Post it if you make one !
The design is inspired from the Spidex Micro from Quaternium.

Printed with 40% filling seems to be rigid enough for fly.
The frame is just good to print on a 200 x 200 bed.
