You assume all responsibility and risk for the use of the supplied 3D model above. If the part fail underwater and you lose a fin, this may have a serious impact on your safety. Please consider using the original part from the manufacturer or a CNC machined part made of metal. Printed parts may and will eventually fail.

Spring fin strap extenders made to extend the spring and reduce the pressure on boots (especially when the 12 inches spring, which is the longest available on the market is too short for you boots).

Transform 12 inches straps into roughly 14 inches.

V2 has the movement restrictor that goes into the round shape of the fin's attachment point.
