Tripod bolt knob and retainer

This is just an addition to a great tripod that Kernal770 designed for action cameras and the like. I loved Kernal's design but wanted the attachment bolt to stay put. This works well. I heated up the bolt and just pressed it into the knob. I then glued the cover over the knob taking care not to seize up the turning of the knob and bolt. I printed the knob and cover at 100% infil for strength. These are small parts so they don't take much time or filament to produce.
