Fishing Lip Grip With Spring

thingiverse

I took the original file and extruded 5mm holes that are 9mm depth on each part this is enough room for a pen spring to be placed inside. I didn't glue the spring at all, it is free-floating but it won't come out since there is a nut and bolt holding the two parts together. When fishing with this the lip grip still holds a fish when holding on to the string due to the weight of the fish and easily opens back up to grab the next one. Enjoy!
