Gopro Hero 9/10 Dummy Cam

thingiverse

I needed a dummy camera to use on my FPV drones so I could fly without risking a gopro when I didn't need to, without getting used to flying a lighter weight quad. So I hollowed out SocramZap's model so I could add the proper amount of weight to it (147g for hero 9, 154g for hero 10). Just add whatever you want to the cavity to get to the desired weight, and glue the end cap on. I used loose change wrapped in plastic wrap to keep it from moving around inside, but whatever you have laying around that's semi-heavy will probably work.
