Improved GoPro Long Thumbscrew
Description
My fingers aren't as strong as they were. I found that the manufacturer's thumbscrews needed extra torque. This one is much easier to turn and tighten. I insert a 5 mm bolt cut to an extra cm or two longer than needed to tighten the mount. I put some CA glue in the open hole at the crank end before finishing screwing the bolt in. That way the last 20 or so threads are locked into the thumb screw. Another way to fasten a bolt is to get a 5 mm bolt that is long enough to go through the plastic to exit through a 5mm nut either heated to melt the plastic, or simply glued at the nut end. It's probably a good idea to print at 100% fill for strength.
