Lipo Guard / Battery Protector

thingiverse

There are a lot of lipo guards out there ... I dunno, most seemed to rely on the elasticity of solid TPU to absorb all the impact. This sorta struck me as heavy and limited in its ability to actually protect the battery from blunt impacts like bottoming out. The "crumple zone" was just the TPU itself. This is designed to (hopefully) really absorb impact with sort of crumple zones built out of arms of flexible filament. In theory this should be lighter and hopefully protect better. I printed it in PCTPE with no support. PCTPE is stiffer than TPU but probably doesn't bridge as well - either way.... if you make one ... let me know how you fair! The battery in the image above is 1400mah and pretty long ... i think this should cover 1300-1500 the back is a little open but I think the props / arms will catch before the battery hits. I think this ended up being ~6-7g when printed in PCTPE
