ZMR 250 Top Plate
I wanted more space on the top plate of my ZMR 250 to hold the Nano-Tech 3S 1300mah LIPO and mobius mount so I utilized the arm plate from this frame design on thingiverse.com

I removed all of the unnecessary holes except for one hole on each of the arm areas. The top plate will be attached to the ZMR 250 frame using aluminum standoffs at these holes.
The Nano-Tech 3S 1300mah LIPO fits nice and snug inside the center box area. I created elongated slots on each side to run a Velcro strap through them.
For convenience, I used an XT60 connector holder from another thingiverse.com design and integrated that into the plate.
The large 7mm holes at one end of the plate next to the XT60 holder are used to attach the video transmitter antenna.
The holes and grid pattern slots on the opposite side of the plate are used to attached a Mobius camera mount.
I created the design in Tinkercad.
