I have been asked many times to release this so I finally decided to. It’s a GoPro knob replacement for the original long one.
You will need to provide the bolt.
Instructions
So just print this as you would anything else. You will need your own bolt, I get mine from Mcmaster Carr. This is there description:
Metric 18-8 Stainless Steel Hex Head Cap Screw, M5 Size, 45MM Length, .8 mm Pitch, Fully Threaded
And their part number is 91287A331
If you want the matching acorn nut it’s part# 94000A037
While the bolt should fit snuggly, I highly recommend using JB Weld to epoxy them in place. Even the originals from Gopro benefit from this.
