Hello, 
I would like to print these little parts for my drone

The battery protector is very useful to prevent battery damages (and potential fire/explosion !)

The LiPo balance plug holder prevent it to be destroyed by the propellers

And the buzzer holder to have a nice and clean mount of the buzzer (very useful to find the drone when it crashes in high grass)

 Edit: I add a rubber pad to print in TPU to protect the LiPo from shocks
