Summary

Easy and quick system to secure and remove your Usbox windsurf fin in a flick of eyes.
It also can serve as a fin saver in case of crash.

There are two versions (both are fully functional):

• Nut located on the bottom (so you can use a locknut to ensure it spins properly inside the track)
• Side allocation nut (looks better, but needs more supports)

Setup:

• Infill: 100%
• Layer Height: 0.2
• Supports: Yes
