A collection of SUP fin designs specifically for Slide-In box mounts (see last picture).

By printing the fin blade flat on its side, you get an incredibly strong part while cutting down on print time. The design features a generic base that can be reused across all the different fin blades—saving you filament, time, and weight in your SUP bag.

Print settings:

  • Infill: 50%

  • Supports: None needed

  • Tested Materials: Successfully tested and proven in both PLA and PETG.

Fin designs:

  • Touring: Features a large surface area with a swept-back leading edge.

    • Improves tracking (straight-line paddling)

    • Improves stability

  • River: A low-profile, shallow-depth design.

    • Less depth, good for shallow waters

    • Less chance to collect tangled river weeds

  • Surf: Smaller pointier profile.

    • Quick, responsive turns and agility in the waves.

  • Shark: An all-around fin size with an aggressive, eye-catching shark fin silhouette.

    • Solid everyday performance

    • Turning heads while your board is resting on the beach!

If you successfully print and use one of these designs, please share a photo! I'd love to see your setup.

Happy supping!
