A printable quadcopter frame! Arms are about 6" long, making the assembled frame 1' by 1'. More info is to come as I have only finished designing and printing the frame.

Insert the arm pieces into the center piece, and then glue on landing gear pieces about 1/4" from the end of each arm. Glue motors on the ends of the arms, and stick electronics and batteries to the center piece.
Again, these instructions might be updated as I progress with the build.
