Mobula 7 batteryholder for large batteries

These holders are designed for [GN3 550mAh batteries](https://www.banggood.com/5Pcs-Gaoneng-3_8V-550mAh-50C100C-Lipo-Battery-PH2_0-Plug-For-Tiny-RC-Helicopter-Drone-p-1348860.html?cur_warehouse=CN) to fit snugly on the Mobula7.
They fit the various Mobula7 frames on Thingiverse.

I can highly recommend these larger batteries over the standard that comes with the small indoor flyers. I get 5+ minutes of flighttime.
