GoPro HERO 11/10/9 lens cap

thingiverse

This is a lens cap for the GoPro HERO 11. Lens caps sold for the HERO 11 are also said to be compatible with HERO 10 and 9, so this should be too, but I don't have any of those to test it with. I designed and printed this, and it fit perfectly on the first try. You may need to shrink or grow it by a percent or so in your slicer if your printer scales it slightly differently. Print the cap with the front down, and you don't need any supports.
