Bixler 1.1v2 battery keeper wall.

thingiverse

Bixler 1.1v2 has an open fuselage, this is great because you have a ton of room for battery and component options. We fly ours with 3S 3000mah zippy flight max batteries, and a friend uses a 3S 2800mah. We noted that the fuselage was not just open, but unsuported with no battery compartment. So I came up with this to add some support, and create a batter area while keeping internal airflow in mind (we added cooling holes to keep the ESC inside to better protect it.) I printed all of ours with just rafts. but you can print it anyway you like. Installation is super simple, take the canopy off, drop this down inside the fuselage with a bit of glue (any kind you prefer, we used foam safe) using two toothpicks you can shove them into the small holes on either side to lock it in. This gives you a way to keep your battery from sliding too far back if the Velcro fails.
