For the first, many thanks to seblaporte for the great design of quadcopter. I made some minor changes:
1) I think, antennas are better in horizontal direction according their radiating characteristic. So I made holder according to this.
2) I made ESC holder.
3) I bought Gemfan propellers 9047, which have bigger hole, than shaft of motor. And they have a chamfer. I made a reduction for these propellers.
4) I made a new holder for camera SJ5000X Elite according the original. For assembly of both parts together you will need 2 screws M3x8 or M3x10 max.
Other items are the same as the original on http://www.thingiverse.com/thing:1541511.
I used for all items of quadcopter material PETG.
