cosmedic shells

I've just started to build the Open Duck Mini and maybe, in a future version, all the electronics and mechanical structure could be an integral assembly and stand alone. The outside shells should be cosmetic only and the droid should be operational without them. So all electronics, wiring, battery, motors and skeleton are on the main frame, make debug and troubleshooting possible without the shells. As with the present design, i need to dismantle part of the head motor structure to put on the top body piece, cause it doesn't fit over the motor structure of the head.
I know a lot of work has gone into this project and i appreciate that, but i don't want this to be discarded because of the additional work involved. Thank you all, for this wonderful project!
