Betafpv 75x Battery Pad

thingiverse

This is a very simple design, it allows you to strap a bigger battery to you betafpv beta75x. It provides a flat surface so you can stick a Velcro pad under the quad. It might work for others, I just have that one. Should be printed in tpu, I recommend printing directly to glass, to have a very flat surface, so you can easily attach the velcro.
