This frame mounts to the Diatone style quad frames. Drew it up to fit my Ghost Edition version. It will probably easily fit other frames as well. It fits my batteries which range from 1000mAh to 1600mAh. Slip some velcro strip through the slots in the side to fix the battery into the holder. "Batt 1" is more of a solid object with a couple holes in the base for using less plastic and lightening it up. "Batt 2" has some slots through the edges to lessen stresses and hopefully lower the chances of warping during printing. I printed mine in ABS with this file since ABS is strong but tends to warp. "Spacer" is a small washer which I needed so the holder would not smash against the innermost LEDs on the bottom. Just print 4 and slip them between the holder and the frame when installing if you need them.
