GoPro knob - short (for 33mm M5 bolt)

This is a GoPro knob for use with a 33mm M5 bolt. Just thread the bolt in and lock it in place with a drip of glue so that the bolt does not come out.

v2 is with a slightly bigger recess in the bottom for the bolt head to fit. The first version is a bit tight (only suitable for screw).
