GoPro tripod adaptor.

thingiverse

I needed a custom-fit adapter for my GoPro camera so I took matters into my own hands and designed one myself after discovering that all available options online were either oversized or didn't meet my requirements.\r\n\r\nThe design features an M5 nut attachment, but upon further inspection, I found that the bolt screws in remarkably tightly and doesn't actually require a nut to secure it. If you do need to use a nut, though, be prepared for a longer-than-standard m5 bolt since the regular GoPro bolt falls woefully short.
