I ruined one of my lipo batteries by pancaking it into the ground so I thought it would be better to have some sort of protector and maybe save that $10 battery.

This is a fully parametric design, you just need to put your battery height, width, length in the bheight, bwidth, and length and then decide how much space you want around the battery (Padding) and how much padding you want between the top of the battery and the top of the holder, width of the battery strap.

I have the settings set for my Tattu 800mah batteries but it will work with any size battery you just need to change the fusion 360 parameters mentioned above.

Bonus feature: it gives the quad a very nice and flat surface to sit on.
