GoPro Lens Cap with Hole
by frankkienl, published
Protect your lens, but still be able to make a video.
You can make the hole bigger or smaller by editting the attached .scad file.
(You also need to download goprohero3lenscap_fixed.stl, ths scad files depends on that file)
Note: I do not have a GoPro, I do not know if they will fit.
print 'gopro lenscap.stl' with 10% rectangle infill, 0.2 layer height, Black PLA.
Its best to print 2 at a time, to make sure the layers get enough time to cool.
