GoPro knob - short (for 33mm M5 bolt)

thingiverse

This is a GoPro knob engineered for use with a 33mm M5 bolt. Simply thread the bolt in and secure it firmly in place by applying a small amount of glue, ensuring the bolt remains tightly fixed. Version two features a slightly larger recess at the bottom to accommodate the bolt head perfectly. In contrast, version one is designed more as a screw, being somewhat too tight for optimal use with bolts.
