RUNCAM 3 orange action camera cage, compatible with FPV drone mount

There isn't a single RUNCAM 3 action camera cage shared on the entire site. Referencing the design from Thingiverse, I designed a model in my spare time during class. The RUNCAM 3 action camera is quite old now; it's a very old product. What you can buy now are all second-hand, and the batteries are also worn out. Don't bother looking for official after-sales service to replace the battery; they don't have stock anymore. If you have the DIY skills, you can replace it yourself, but many of the batteries you buy will have inflated specifications, so there's no difference whether you replace it or not. The suggestion is to DIY one that draws power from a balance connector, then steps down the voltage to a 5V 1A USB-C port, to continuously power the camera during flight, charging while using. However, the drone's flight time will decrease. Please weigh your options accordingly.
