GoPro Hero 7 Black Lens Cap

thingiverse

I needed a better lens cap for my GoPro that wouldn't fall off easily. Not worried about damaging it, but fingerprints and grease can be a problem until I'm ready to use the camera. A cheap silicone one works okay, but it keeps coming loose when I put the camera in my pocket. Figured a tighter-fitting one from the 3D printer would do the trick. These ones fit pretty well, though how tightly they fit will depend on your printer and its resolution. (Printed mine on a Prusa.) If they're too loose, you can just size them down a bit and try again. I'm using version 2 right now. Version 3 has corners that are rounded out to try to get them even tighter to the actual profile of the GoPro's lens cover. Haven't tried those yet since version 2 works fine for me.
