Printed no problems with Slic3r support turned on. The font of the creator's name could be thicker as my 0.6mm nozzle could not fill it in. Could be maybe 1-2mm deeper (Y axis, toward the antenna) as this has a little bit of play. I will probably install a piece of neoprene craft foam on one side to take up the slack. I used spring terminals on one side and a "bumped" terminal on the other, however the bump on the terminal wasn't long enough to make contact with the battery so I just soldered a tiny piece circle of 20AWG solid wire to the bump contact to make a connection.
With 3500mAh batteries, 20 hours or more of flight time is possible. I've never worn these down completely so I don't know just how long it can run.
